[repacker] make repacker object ids stable.
Prior to this change the object id for a vertex in the repacker graph is it's position in the topological ordering. As a result after each sorting the object ids change. This decouples the topological sorting from the object id assignments. A separate ordering list is retained. This simplifies handling around object ids which no longer needs to account for them shifting, and improves performance by eliminating the step of reassigned link object ids after each sort.

[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 https://github.com/skef/harfbuzz/commit/3ae2fe2084d96f61d8ad1bbe42a6ef4e62ec830a rebased onto head w/ tests added.

[instance] add tests for featureVariations
Also updated the script that is used to generate tests.With fonttools,
we now do instancing first and then subsetting.
With different order of subsetting and instancing operations on the same
VF file, fonttools seems to generate 2 different font files with different
glyph set.
1. do subsetting and then instancing: this seems result in a larger glyph
set in the font file. Lookups are collected from both retained features
and all possible alternate featurevariations, this leads to a larger
glyph set after glyph closurei. And instancer doesn't redo glyph
closure, it does lookups pruning only.
2. do instancing and then subsetting: lookups are collected from
features that are replaced already and possible alternate feature
variations

[subset] Fix cpal subsetting when there are partial palette overlaps.
The existing code doesn't correctly handle the case where palettes partially overlap in the color record array. This changes the subsetting to only share entries in the color record array when palettes have the same first color index. Partially overlapping palettes will be converted to disjoint segments in the color record array.
Updates one of the color tests to use multiple palettes.
Also fixes fuzzer: https://oss-fuzz.com/testcase-detail/5568200165687296.

we should not cache visited langsys cause 2 different Record<Langsys>
could have different Tag while pointing to the same Langsys, a langsys
is redundant in Record<Langsys> A does not mean it's redundant in Record
B. Same thing for visited_script.
Also adding the number of features in the LangSys's feature list to the
visited langsys count so it's more accurate.
Plus some improvement in langsys compare()

[subset] (Chain)ContextSubst glyph_closure fix
- When pos_glyphs is empty, use current full glyphs set as input for
subsequent recursive closure process
- Also increase max_lookup_visit_count to 35000 cause a real font file hit
previous limit 20000 and some lookups are dropped unexpectedly

[subset] MATH: don't serialize coverage table when iterator is empty
when iterator is empty, just set coverage offset to 0.
serialize() in coverage will at lease write out a 16-bit format header.
