[subset] Update hb_subset_input_override_name_table API
...
Override the name string for the NameRecord identified by name_id,
platform_id, encoding_id and language_ids specified by the user.
If a record with specified name_id does not exist, this API will create
a new NameRecord with provided info and insert it to the name table.

[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

[CoverageFormat2] Remove hand-written loop
...
While on a fuzzer-found test case (added) that loop was faster,
on real fonts, including NotoNastaliq in our benchmark, it was
actually slower, which intuitively I would have expected.
Still no idea why on that fuzzer case it's faster though. :(
