Unfork AnimatedPropSerializer.cpp override added during 0.85 nightly integration

[anuagragith]

Problem Description

During the integration of RN 0.85.0-nightly-20260128-36f07a1b2 (#16245), the upstream AnimatedPropSerializer.cpp uses Color as a plain int32_t, but on Windows Color is a struct. This required a local patched copy with a helper function to convert Windows Color to int32_t ARGB format.

Current Fix
A local patched copy was created at vnext/ReactCommon/TEMP_UntilReactCommonUpdate/react/renderer/animationbackend/AnimatedPropSerializer.cpp with a colorToInt32() helper that calls color.AsWindowsColor().
