Support for COLR 0xFFFF foreground color in FT backend
COLR fonts can use a magic palette index value 0xFFFF to
indicate the foreground color of the drawing context. Support this by
defining a flag plus saving the foreground palette value on the
SkScalerContextRec when creating the SkStrikeCache entry. Then the
FreeType backend can use the palette value when performing the COLR
drawing runs.
