Cherry-pick: Define SK_USE_FREETYPE_EMBOLDEN on Android

(From by
Colored Emoji not drawn in Chrome if font style is set as Bold.
When Bold font is asked, then Skia try to generate image/bitmap from
path (if Bold font is not present) which is not correct case for Colored
Emoji bitmap font.)

Define SK_USE_FREETYPE_EMBOLDEN to prefer FreeType's emboldeing
algorithm to Skia's.
