Garret Rieger ea1ee0d4b6 [instance] drop and don't collect lookups from feature variations when fully instancing.
This previously incorrectly collected lookups that could be reached via feature variations that are dropped and not activated by the current instance position.

Behdad Esfahbod 24a4d397ba [aat] Allow disable feature ranges
Fixes https://github.com/harfbuzz/harfbuzz/issues/4020

This is a hack.

To implement this properly we need to treat runs with different features
as independent runs for running the state machine, as the subtable flags
might be different. That would be a significant change to our internal
implementation.

Qunxin Liu 1eb5445e75 [subset] Fix issue in hb_subset_input_override_name_table()
If a nameRecord with provided name_id/platform_id/encoding_id/lang_id
is not retained after subsetting, create it and insert it to
the name table. So we need to check against retained name_records
rather than name_record in the original name table.
