common capi: Added opacity C bindings.

Added opacity setter/getter to CAPI. They will be useful to simplify
code responsible for set visiblility of paint.

@API Additions:
Tvg_Result tvg_paint_set_opacity(Tvg_Paint* paint, uint8_t opacity)
Tvg_Result tvg_paint_get_opacity(Tvg_Paint* paint, uint8_t* opacity)
