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.

rather than name_record in the original name table.
