[aat] Consume glyph insertion from buffer's max_ops (#2223) 
Glyph insertion is an expensive operation and we like to have it limited
based on buffer's input size which is handled by buffer's max_ops.

clusterfuzz-testcase-minimized-harfbuzz_fuzzer-5754958982021120:

Before the change: 0.67s user 0.00s system 99% cpu 0.674 total
 After the change: 0.02s user 0.00s system 98% cpu 0.024 total

Which takes much longer on valgrind and tsan bots.

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.

Fixes #2441

Ebrahim Byagowi a9d13463b5 [meson] Categorize tests using `suite: [...]`

  meson test -Cbuild test-shape --print-errorlogs

Ebrahim Byagowi c68ab4b52b Fix _get_ligature_caret's oob read issue 
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.
