[paint] Pass hb_paint_context_t along

Replace the font argument with a hb_paint_context_t

index and the foreground color as extra arguments.

[subset] optimize glyf subsetting w/ retain gids.
...
When retain gids is enabled the subset plan may require the output of many empty glyphs. This change optimizes the glyf subsetting code when the number of retained glyphs << number of output glyphs. Unnessecary lookups to the glyph map are reduced by iterating through the glyph map instead of the output glyph set.
