[subset] optimize glyf subsetting w/ retain gids.
...
When retain gids is enabled the subset plan may require the output of many empty glyphs. This change optimizes the glyf subsetting code when the number of retained glyphs << number of output glyphs. Unnessecary lookups to the glyph map are reduced by iterating through the glyph map instead of the output glyph set.

[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

meson: Fix freetype and icu dependency lookup
...
It is wrong to search for a different name depending on the compiler. If
anything, cmake name could be available on systems that uses GCC too.
This also fix regression in the usage of freetype subproject fallback as
its name is "freetype2" and was previously used even when the
"freetype" option was set to "auto".
