[Android] Update HostPlatformColor to support color longs

[ryanlntn]

Summary:

This adds support for color longs to HostPlatformColor per the wide gamut color RFC.

Changelog:

[ANDROID] [ADDED] - Update HostPlatformColor to support color longs

Test Plan:

This requires changes from #43030 to build and will only break text color until those components are updated to support color long values as well. Will update with a link to that PR soon.

Could we document what the magic numbers are doing? Maybe pull them out into constants?

@NickGerleman I pulled out the color space and component ratios definitions into constants. Should I do similar with the bit masks/shifts? I can't decide what's more readable.

The shifts seem reasonably readable to me
