Summary:
## Problem
For some reason, D20831545 broke the `use_frameworks!` build of RNTester.
## Building RNTester
```
pushd ~/fbsource/xplat/js/react-native-github/RNTester && USE_FRAMEWORKS=1 pod install && open RNTesterPods.xcworkspace && popd;
```
## Error
I built RNTester locally, and the error was this:
```
Undefined symbols for architecture x86_64:
"facebook::jsi::HostObject::set(facebook::jsi::Runtime&, facebook::jsi::PropNameID const&, facebook::jsi::Value const&)", referenced from:

vtable for facebook::react::ObjCTurboModule in RCTImageStoreManager.o
ld: symbol(s) not found for architecture x86_64
```
## Fix
It looked like libraries that depend on "ReactCommon/turbomodule/core" weren't linking to JSI correctly. So, I modified all such Podspecs to also depend on "React-jsi":
```
arc rfr ' s.dependency "ReactCommon/turbomodule/core", version' ' s.dependency "ReactCommon/turbomodule/core", version\n s.dependency "React-jsi", version'
```
This seemed to do the trick. In buck, we'd fix this problem using exported_dependencies. I skimmed through cocoapods, and couldn't find such a configuration option there. So, I guess this will have to do?

Summary:
As part of the fix for https://github.com/facebook/react-native/issues/25349 I added `s.static_framework = true` to each podspec in repo (see https://github.com/facebook/react-native/pull/25619#discussion_r306993309 for more context).
This was required to ensure the existing conditional compilation with `#if RCT_DEV` and `__has_include` still worked correctly when `use_frameworks!` is enabled.
However, fkgozali pointed out that it would be ideal if we didn't have this requirement as it could make life difficult for third-party libraries.
This removes the requirement by moving `React-DevSupport.podspec` and `React-RCTWebSocket.podspec` into `React-Core.podspec` as subspecs. This means the symbols are present when `React-Core.podspec` is built dynamically so `s.static_framework = true` isn't required.
This means that any `Podfile` that refers to `React-DevSupport` or `React-RCTWebSocket` will need to be updated to avoid errors.
## Changelog
I don't think this needs a changelog entry since its just a refinement of https://github.com/facebook/react-native/pull/25619.

Test Plan:
Check `RNTesterPods` still works both with and without `use_frameworks!`:
1. Go to the `RNTester` directory and run `pod install`.
2. Run the tests in `RNTesterPods.xcworkspace` to see that everything still works fine.
3. Uncomment the `use_frameworks!` line at the top of `RNTester/Podfile` and run `pod install` again.
4. Run the tests again and see that it still works with frameworks enabled.

Summary:
This is my proposal for fixing `use_frameworks!` compatibility without breaking all `<React/*>` imports I outlined in https://github.com/facebook/react-native/pull/25393#issuecomment-508457700. If accepted, it will fix https://github.com/facebook/react-native/issues/25349.
It builds on the changes I made in https://github.com/facebook/react-native/pull/25496 by ensuring each podspec has a unique value for `header_dir` so that framework imports do not conflict. Every podspec which should be included in the `<React/*>` namespace now includes it's headers from `React-Core.podspec`.
The following pods can still be imported with `<React/*>` and so should not have breaking changes: `React-ART`,`React-DevSupport`, `React-CoreModules`, `React-RCTActionSheet`, `React-RCTAnimation`, `React-RCTBlob`, `React-RCTImage`, `React-RCTLinking`, `React-RCTNetwork`, `React-RCTPushNotification`, `React-RCTSettings`, `React-RCTText`, `React-RCTSettings`, `React-RCTVibration`, `React-RCTWebSocket` .
There are still a few breaking changes which I hope will be acceptable:
- `React-Core.podspec` has been moved to the root of the project. Any `Podfile` that references it will need to update the path.
- ~~`React-turbomodule-core`'s headers now live under `<turbomodule/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511091823.
- ~~`React-turbomodulesamples`'s headers now live under `<turbomodulesamples/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511091823.
- ~~`React-TypeSaferty`'s headers now live under `<TypeSafety/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511040967.
- ~~`React-jscallinvoker`'s headers now live under `<jscallinvoker/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511091823.
- Each podspec now uses `s.static_framework = true`. This means that a minimum of CocoaPods 1.5 ([released in April 2018](http://blog.cocoapods.org/CocoaPods-1.5.0/)) is now required. This is needed so that the ` __has_include` conditions can still work when frameworks are enabled.
Still to do:
- ~~Including `React-turbomodule-core` with `use_frameworks!` enabled causes the C++ import failures we saw in https://github.com/facebook/react-native/issues/25349. I'm sure it will be possible to fix this but I need to dig deeper (perhaps a custom modulemap would be needed).~~ Addressed by https://github.com/facebook/react-native/pull/25619/commits/33573511f02f3502a28bad48e085e9a4b8608302.
- I haven't got Fabric working yet. I wonder if it would be acceptable to move Fabric out of the `<React/*>` namespace since it is new? �
## Changelog
[iOS] [Fixed] - Fixed compatibility with CocoaPods frameworks.
Pull Request resolved: https://github.com/facebook/react-native/pull/25619
Test Plan:
### FB
```
buck build catalyst
```
### Sample Project
Everything should work exactly as before, where `use_frameworks!` is not in `Podfile`s. I have a branch on my [sample project](https://github.com/jtreanor/react-native-cocoapods-frameworks) here which has `use_frameworks!` in its `Podfile` to demonstrate this is fixed.
You can see that it works with these steps:
1. `git clone git@github.com:jtreanor/react-native-cocoapods-frameworks.git`
2. `git checkout fix-frameworks-subspecs`
3. `cd ios && pod install`
4. `cd .. && react-native run-ios`
The sample app will build and run successfully. To see that it still works without frameworks, remove `use_frameworks!` from the `Podfile` and do steps 3 and 4 again.
### RNTesterPods
`RNTesterPodsPods` can now work with or without `use_frameworks!`.
1. Go to the `RNTester` directory and run `pod install`.
2. Run the tests in `RNTesterPods.xcworkspace` to see that everything still works fine.
3. Uncomment the `use_frameworks!` line at the top of `RNTester/Podfile` and run `pod install` again.
4. Run the tests again and see that it still works with frameworks enabled.

Summary:
This is an ESLint plugin that infers whether an import looks like a Haste module name. To keep the linter fast and simple, it does not look in the Haste map. Instead, it looks for uppercase characters in single-name import paths, since npm has disallowed uppercase letters in package names for a long time. There are some false negatives (e.g. "merge" is a Haste module and this linter rule would not pick it up) but those are about 1.1% of the module names in the RN repo, and unit tests and integration tests will fail anyway once Haste is turned off.
You can disable the lint rule on varying granular levels with ESLint's normal disabling/enabling mechanisms.
Also rewrote more Haste imports so that the linter passes (i.e. fixed lint errors as part of this PR).

Summary:
This is the next step in moving RN towards standard path-based requires. All the requires in `Libraries` have been rewritten to use relative requires with a few exceptions, namely, `vendor` and `Renderer/oss` since those need to be changed upstream. This commit uses relative requires instead of `react-native/...` so that if Facebook were to stop syncing out certain folders and therefore remove code from the react-native package, internal code at Facebook would not need to change.
See the umbrella issue at https://github.com/facebook/react-native/issues/24316 for more detail.

Summary:
This PR implements the first part of [RFC0004: CocoaPods Support Improvements](https://github.com/react-native-community/discussions-and-proposals/blob/353d44f64957113409eb16f836e23dba396a6b46/proposals/0004-cocoapods-support-improvements.md), splitting the `React.podspec` into separate podspecs to more closely match the structure of Xcode projects.
The new structure aims to have one to one mapping between Xcode projects and podspecs. The only places where we differ from this mapping are:
* `React/React-DevSupport.podspec`: `DevSupport` is a part of `React.xcodeproj`, which corresponds to the `React-Core` pod. However, we can't include it in the `React-Core` pod because `DevSupport` depends on `React-RCTWebSocket`, which depends on `React-Core`. Pods may not have circular dependencies.
* The new pods under `ReactCommon/` don't have a corresponding `xcodeproj` because there are no `xcodproj` files in `ReactCommon/`. Those C++ modules are included in `React.xcodeproj`.
*Next steps (not in scope of this PR):*
- Start submitting the Podspecs to CocoaPods on a deploy (or turn the React Native repo into a spec repo): this is important in order to make the experience nicer for library consumers, so that it's not necessary to specify the local path of each Podspec in `Podfile`, you can just add `pod 'React', <version>`.
- Add `Podfile` to the default project template (I have a PR ready for this, but because of bugs related to subspecs, it's blocked on this PR)

TurboModules depend on a getConstants method. Existing ObjectiveC modules do not have this method. Therefore, I moved the contents of `constantsToExport` to `getConstants` and then had `constantsToExports` call `getConstants`.

Since all NativeModules will eventually need to be migrated to the TurboModule system, I didn't restrict this to just the NativeModules in Marketplace.

This changes our xcode setup to use a copy files phase instead.
I've also changed the header include path to be $(BUILT_PRODUCTS_DIR)/include, which is added to the include path by Xcode by default, so 3rd party libraries should not be impacted by these changes anymore.

If your xcode project still has a custom header include path, both variants will likely continue to work, but for new projects, we're defaulting the header include path to `$(BUILT_PRODUCTS_DIR)/usr/local/include`, where the React and CSSLayout targets will copy a subset of headers too. To make Xcode copy headers phase work properly, you may need to add React as an explicit dependency to your app's scheme and disable "parallelize build".

Summary: Correct header import paths, update podspec so we point at the copy in ReactCommon (and can eventually remove the copy under React)
