Garret Rieger c0f3af91b8 [subset] speed up add_gid_and_children and adjust op limit.
Fix for fuzzer timeout: https://oss-fuzz.com/testcase-detail/5001604901240832.

- Operation limit is per glyph, so 100,000 should still be far more than needed.
- Switches from for(...) to while(...) loop for iteration. for(...) calls it.end() which in this case triggers a complete iteration.
- Cache CompositeGlyph size in the iterator to avoid needing to recalculate it.

Khaled Hosny 7ccc52b075 [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The expected files have been replaced by hb-subset output so they are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.

[aat] Correct array indexing when looking up actions in KerxSubTableFormat4 (#2539)
* [aat] Correct array indexing when looking up actions in KerxSubTableFormat4.

- For action_type 0 and 1, there are 2 values per action record; for action_type 2, there are 4. So we need to account for these factors when indexing into the ankrData array.

whole ligature caret is low use but guess we better to encourage GDEF one anyway.

Christoph Reiter 03bd6ead44 [meson] Only pass required dependencies to everything
Instead of passing dependencies as required we used one giant shared
dependency list containing all dependencies for every library/executable.
While this kinda works, the specified deps are also used for generating
the pkg-config files and this leads to lots of Requires.private and Libs.private
entries which aren't really needed.

This removes the "deps" array and replaces it with a few smaller ones and
makes sure the public libraries only get passed the dependencies actually
needed.

AAT::Lookup has no other way to detect whether it is returned from
a real and sanitized font data or from a null pool, this checks if
the table has been recognized valid by sanitizer by checking
table's major version which is zero if returned from a null pool and
non-zero if is from a sanitized font data, it is expected the other
calls of the table (unlikely to have more calls however) also do a
similar version check before calling the lookups used on the table.

visual breakage reported in #2358).

Christoph Reiter 8ae06c9489 meson: build a separate library for harfbuzz-icu
This adds a seperate library like with autotools.

This also fixes the ico feature option which was just set to required:false
when disabled instead of really disabling it.
Disabling is still broken with msvc because it then tries to find the library
another way, but that's broken for all other deps as well so I left it as is.

For tests only test-unicode.c is using icu specific functions so split it out
into its own category which depends on harfbuzz-icu.
