This creates a new feature flag to enable the modern Web performance APIs in RN by default. It's disabled by default so it shouldn't have any effect at the moment.

Follows D72228547 and D73770609.
This diff internalises (moves files from fbsource+GitHub to fbsource only) a number of RNTester examples which referenced `'react-native/src/private/'` subpaths.
In future, new components/APIs should be exported from index as `unstable_`, or added to `RNTesterListFbInternal` if they are exported from `src/fb_internal/`.

The PerformanceObserver (marks and measures) example clears it's output each time a new PerformanceObserver event fires, which makes it not particularly useful.
This change makes it so the output is only updated if a non-empty list of performance events is observed.

Replaces *many* `Text` component usages with `RNTesterText`: a thin wrapper around `Text` that applies color based on the color scheme chosen by the user. It makes text legible for dark mode across 41 different example files. This changes intentionally do not touch a few larger component sites that expand beyond RNTester, like `Animated` and `NewAppScreen`

This improves the example in RNTester for `performance.mark` and `performance.measure` by only listing the marks/measures explicitly emitted from the example. This removes noise if other parts of the app are logging marks/measures as well.

Summary:
Changelog: [internal]
(this functionality hasn't been enabled in OSS yet, so no changelog necessary).
Fix https://github.com/facebook/react-native/issues/45122.
performance.mark is currently O(1) but performance.clearMark is O(n) (being n the number of entries in the buffer), which makes this operation very slow.
### Changes overview
- Created new `PerformanceEntryBuffer` abstraction with the following subtypes, that differ on how entries are stored:
- `PerformanceEntryCircularBuffer` - stores them in a ring buffer that was already implemented, removed key lookup cache (`BoundedConsumableBuffer`)
- `PerformanceEntryKeyedBuffer` - stores them in a `unordered_map`, allowing for faster retrieval by type
- `PerformanceEntryLinearBuffer` - a simple infinite buffer based on `std::vector`, currently used in a `PerformanceObserver`
- Created `PerformanceObserver` abstraction on native side.
- Created `PerformanceObserverRegistry` that collects active observers and forwards entries to observers that should retrieve them
- Moved some method implementations to `.cpp` files to reduce potential compilation time slowdown. As the `PerformanceEntryReporter` can be included from anywhere in the code, it will be beneficial to make header files as light as possible.
- Add comments to methods that note which standard is the method from/for.
- Added some `[[nodiscard]]` attributes
- Since the logic of routing entries to observers is moved to native side, JS side of the code got much simplified
- If ever needed, `PerformanceObserver` can be created from native-side

Test Plan:
I've tested this e2e on IGVR and in the RNTester playground for the performance APIs. Everything works as expected.
There are also new unit tests for this.

This is a basic implementation of the Long Tasks API (https://w3c.github.io/longtasks/).
It detects and reports long tasks when using the Event Loop (in the modern RuntimeScheduler) when a new feature flag for this purpose is enabled.
This doesn't include attribution information at the moment.

This change makes the returned values from `performance.reactNativeStartupTiming` to accept null or undefined. This is done as some platforms may not have certain startup timing information, and as a default value, it's discussed that null/undefined is better than zero.
- Use `unorderedMap` instead of custom timing object for the C++ native module return value
- Use `std::nan` as initialized value for unset doubles
- Update examples to reflect the latest changes

Summary:
Right now RNTestePage either adds a large spacer to the end of content, unless `noSpacer` is added. But with `noSpacer`, scrolling content may not be reachable because we are putting padding on the wrong container.
This fixes that and removes a few cases where we had multi hundred px empty space in favor of uniformly taking up the parent, and a 10px padding. This also moves the constant margin at the top of RNTesterBlock to the container, so that in the E2E container we can save the 30px.

Summary:
This diff adds the `performance.reactNativeStartupTiming` API to the performance global object for RN. This property does not exist in web, and we are free to make up our own list of properties in the startup metrics to track RN app startup process. In our case, we have the following six properties to begin with (we may extend and add more to this list in the future):
```
- `(start|end)Time`: The time ‘zero’ for the startup timing and the end of app startup. RN has no knowledge of app start time, which will be provided by the platform. The `endTime` will be the time when the first JS bundle finishes executing (Note that RN supports multiple JS bundles, which can be loaded async)
- `executeJavaScriptBundleEntryPoint(Start|End)`: The time for RN to execute the JS entry point (and finish all sync job)
```
