Support animating text color with native driver

Summary:
Typically, ReactTextView#setText is called via ReactTextViewManager#updateExtraData, but natively animated color changes bypass render and layout pass via direct call to SurfaceMountingManager#updateProps from UIManager#synchronouslyUpdateViewOnUIThread.

Thus, for animated color changes to get applied, we need to handle the color prop in ReactTextAnchorViewManager.

In addition, native driver updates are not synchronized with Fabric's mounting; if the native driver update happens before mount, the update is done in updateState.
