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

a9d13463b5 [meson] Categorize tests using suite: [...] 
So one can run a category of interested tests like

  meson test -Cbuild --suite aots --suite src --print-errorlogs

Intead issuing particular tests which also is possible like

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

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.

collect_unicodes() with clamp, calling add_range() 
Use add_range instead an inner loop, clamp its input number by
number of glyphs a face has.

Even the face cmap12 and 13 have 32-bit hb_codepoint_t, which is here
used to make timeout, face's maxp has 16-bit gid limitation at least for now,
using that makes sure we both fix and the timeout and don't need to change
much things here also in order to support 32-bit gids also someday.
