Summary:
`isColorMeaningful` is the only place in xplat code that currently uses `colorComponentsFromColor`, which assumes that a color is an RGBA value. When implementing `PlatformColor` for windows, where colors might be complex patterns or effects, I'd like to keep the details of `SharedColor` isolated within `SharedColor`. This change moves `isColorMeaningful` into `color.cpp`, where each platform can provide an implementation that takes into account its platform specific color capabilities.
See https://github.com/microsoft/react-native-windows/pull/7801 for an example of window's SharedColor which can be either an RGBA value, or a name of a native color/brush.

[Internal] [Changed] - Move isColorMeaningful to platform specific code
Pull Request resolved: https://github.com/facebook/react-native/pull/31557
Test Plan: This shouldn't change any of the code, its just moving the existing function - normal CI/automation should be plenty of validation.

Summary:
Currently, there is a bug with the way that fabric translates float values for color components to hex/int value (which android uses). There are two main problems with the current setup. The first is that we are using 256 as our ratio instead of 255 which is the maximum value for any color component in hex. The second is that we cast the components to ints instead of rounding which truncates the values. We uncovered this with UIQR because our off-by-one color values were incorrectly off a little bit extra for fabric surfaces.

Summary:
This fixes a recently introduced crash in `colorComponentsFromColor()` (iOS implementation) caused by dereferencing a null pointer.
The fix is just a copy of a code fragment from a previous implementation.

Summary:
Finally, this diff changes the internal implementation of SharedColor to be `optional<int>`.
Initially, when we started working on the new renderer, it seemed like a good idea to allocated CGColor objects ahead of time and store them with Props. Now, this idea does not look so good, especially because:
* Having `SharedColor` as a `shared_ptr` is a quite big perf overhead for copying this thing. And the size of the object is not small.
* Having `SharedColor` as a `shared_ptr` creates huge interconnectedness among pieces of the core and rendering. E.g. improper releasing a pointer in some component view can cause a crash somewhere in the core (because both places might use the same shared `blackColor`.
On Android, we already use simple `int` as a representation of a color, and this works great. And this diff implements something very similar to Android, but a bit differently: here we use `optional<int>` instead of custom class with a single `int` field and some magic value that represents "empty value".
This approach should fix T75836417 because now we don't have allocation and deallocation when we simply assign color values.
If this solution works fine on iOS, I will do unify all implementations among all platforms.
