Fix selectionColor doesn't style Android TextInput selection handles (#…

…31007)

Summary:
This issue fixes #30283 selectionColor does not change the handles color.

The method setCursorColor changes the cursor color of field `mCursorDrawable` using a reflection for Android Devices lower then API 28. This fix adds a reflection to change color of the left, center and right handles of a selection (mTextSelectHandleLeftRes, mTextSelectHandleRes and mTextSelectHandleRightRes).
