[subset] Make cmap4 packing more optimal.
The current CMAP4 implementation uses whatever the current codepoint ranges are and then encodes them as indivudal glyph ids or as a delta if possible. However, it's often possible to save bytes by splitting up existing ranges and encoding parts of them using deltas where the cost of splitting the range is less than encoding each glyph individual.

[subset] During LigatureSubstFormat1 subsetting always place Coverage last.
In Windows 7 on Chrome if the coverage table comes before any of the LigatureSet or Ligature subtables the font won't load. This changes the packing order to always place the Coverage table last. Virtual links are used to ensure the repacker maintains the desired ordering.
Coincidentally fontTools also does the same thing (https://github.com/fonttools/fonttools/blob/a3f988fbf621142d7d9b3e68a69725b88f358869/Lib/fontTools/ttLib/tables/otTables.py#L1137) to reduce overflows during packing.

[subset] discard extra copies of a table in face builder.
Fixes #2361. Stores tables in the builder in a hashmap so you end up with at most one copy of each table. Table serialization order is now based on tag sort order instead of order of insertion into the builder.

[test] Compare sha256 hash before TTX dumps
Most of time the files are identical, so instead of comparing the TTX
dump we can check sha256 hashes of the files first and if they match, we
don’t have to check the TTX dumps at all, making the subset tests orders
of magnitude faster.
time meson test --suite=subset down from:
real 0m19.418s
user 0m38.171s
sys 0m3.587s
to:
real 0m3.102s
user 0m8.622s
sys 0m1.701s
The expected files have been replaced by hb-subset output so they are
bit-identical where FontTools output might not.
The generate-expected-outputs.py now compares the hb-subset output with
fontttols subset and errors of they don’t match.

[test] Speed-up subset tests by saving TTX dump
Speed-up subset tests by saving TTX dump of expected output instead of
generating it each time the tests are run.
Cuts down meson test --suite=subset on my system from:
real 0m38.977s
user 1m12.024s
sys 0m10.547s
to:
real 0m22.291s
user 0m44.548s
sys 0m9.221s
