9701b0024e [subset] Always place CFF1/2 char strings at the end of the packed table. 
Makes the behaviour from HB_SUBSET_FLAGS_IFTB_REQUIREMENTS the default.

c6884377ec [subset] Add HB_SUBSET_FLAGS_IFTB_REQUIREMENTS flag. 
When enabled the output subset conforms to the requirements for a base font to be patched by IFTB patches. IFTB is a proposed incremental font transfer patch. This new flag is set as experimental. Currently, setting this flag causes the output subset to also use long offsets for outline data in loca/glyf, gvar, CFF, and CFF2.

This change is a version of 3ae2fe2084 rebased onto head w/ tests added.

bbd53fcfa4 Remove glyph_map test that uses retain gids. 
We no longer allow the use of glyph map + retain gids (see: https://github.com/harfbuzz/harfbuzz/blob/main/src/hb-subset-plan.cc#L817). Also add the test to the meson file so it will be run by default.
