2175f5d050 [subset] Fix inefficient ItemVariationStore subsetting w/ retain_gids. 
ItemVariationStore is relying on the assumption that the inner_map is populated for all output glyphs, this is not true for subsetting operations with retain gids enabled. Fixes fuzzer timeout: https://oss-fuzz.com/testcase-detail/4575222591520768.

ddd0f7f40b [subset] Add a test for CFF2 instancing. 
Adds option to disable the fonttools comparison check in the test. This is needed since CFF2 instancing is not yet supported in fonttools.

af1e605be2 [instancer] bug fix 
It's possible that length of all_points equals to 4 for non-empty
glyphs: a composite glyph which contains only one child glyph that is
empty.

d5fc4a73c0 [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

b051f3fa83 [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.
