We need to do this to break a dependency cycle that would happen if we try to have `view` depend on `mounting` just to add some telemetry to `view`.

Summary:
Now we not only measure how many times we measured text but also measure how much time it takes. This way we can see which portion of the layout process is spent by layout itself (and measuring embedded components).

Summary:
This change maps the three most used colors (black, white, clear) to corresponding predefined values in UIColor. This should meaningfully reduce the overall amount of allocated UIColor/CGColor objects. In my non-scientific measures, it reduces the number of CGColor objects from ~1500 to ~1000. And... it no much at least in terms of kilobytes. However, I still think it's a good idea to implement this because I hope that can remove some work from memory allocation infra and maybe enable some optimizations that UIKit hopefully does for black and white colors. (I tend to believe that this optimization exists because UIKit even has a classes called UIDeviceWhiteColor and UICachedDeviceWhiteColor.)

Summary:
This diff changes the implementation of `RCTCreateCGColorRefFromSharedColor` and `RCTUIColorFromSharedColor` in such a way that they don't rely on the fact that SharedColor is actually a `shared_ptr<CGColorRef>`. Instead, the methods just extract color components from SharedColor and create UIColor and CGColorRef objects on demand.
This allows us to change the implementation of SharedColor without worrying much about the rest of the system, which will do in the next diff.

Summary:
I noticed when porting my iOS app to macOS via Catalyst that the text rendering was somewhat different on the two platforms. Text looked blurry and over-weight on macOS, even when disabling the Catalyst scaling transform.
I hazily remembered that I'd seen this problem before in my old Cocoa development days: this kind of blurring occurs when rendering text with sub-pixel anti-aliasing into an offscreen buffer which will then be traditionally composited, because when the SPAA algorithm attempts to blend with the underlying content (i.e. in the offscreen buffer), there isn't any. SPAA is disabled on iOS, so the issue wouldn't appear there. On macOS, typical approachs to displaying text (e.g. `CATextLayer`) normally disable SPAA, since it's been incompatible with the platform's compositing strategy since the transition to layer-backed views some years ago. But React Native uses `NSLayoutManager` to rasterize text (rather than relying on the system render server via `CATextLayer`), and that class doesn't touch the context's font smoothing bit before drawing.
This change makes macOS/Catalyst text rendering consistent with iOS text rendering by disabling SPAA.
It appears that the code I've modified is in the process of being refactored (for Fabric?). It looks like [this](https://github.com/facebook/react-native/blob/8d6b41e9bcede07fb627d57cf6c11050ae590d57/ReactCommon/react/renderer/textlayoutmanager/platform/ios/RCTTextLayoutManager.mm#L111) is the corresponding place in the new code (sammy-SC, is that right?). I'm happy to include a change to the new renderer in this patch if someone can point me at how to test that change.
## Changelog
[iOS] [Fixed] - Improved text rendering on macOS Catalyst
Pull Request resolved: https://github.com/facebook/react-native/pull/29609
Test Plan:
1. Prepare RNTester for running on macOS (or apply [this patch](https://gist.github.com/andymatuschak/d0f5b4fc1a28efc4f860801aa1deddcd) to handle parts 1 and 2, but you'll still need to do part 3):
1. Open the workspace, navigate to the `RNTester` target's configuration, and check the "Mac" checkbox under "Deployment Info.
2. Flipper doesn't yet compile for Catalyst (https://github.com/facebook/react-native/issues/27845), so you must disable it by: a) commenting out `use_flipper!` and `flipper_post_install` in the Podfile, then running `pod install`; and b) removing the `FB_SONARKIT_ENABLED` preprocessor flags in the Xcode project.
3. macOS has different signing rules from iOS; you must set a development team in the "Signing & Capabilities" tab of the `RNTester` target configuration pane. Unfortunately, you must also do this in the `Pods` project for the `React-Core-AccessibilityResources` target ([this is an issue which CocoaPods must fix](https://github.com/CocoaPods/CocoaPods/issues/8891)).
2. Run RNTester with and without the patch. You'll see that the font hinting is overweight without the patch; see screenshots below (incorrect rendering above, correct rendering below; note that fonts still remain slightly blurred because of Catalyst's window scaling transform, but that's removed on Big Sur).
