Qunxin Liu f4813e3b7f [instance] update collect_lookups/prune_features()/closure_features() with variations 
Some features will be substituted with variations, so we do not collect
lookups from the original feature tables.

Khaled Hosny d827a5ee40 [subset] Skip glyph closure for any dropped table 
If COLR or MATH tables are being dropped, there is no point in closing
glyphs over them, just like it is done for GSUB.
