[aat] Remove lcar support
...
Very low use, only two distinct font files, Apple Chancery.ttf and Hoefler Text.ttc
have it so it really doesn't worth the size addition and so, but one may argue that
whole ligature caret is low use but guess we better to encourage GDEF one anyway.

[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.

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.

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.

[meson] fix spurious warning when building test/api C sources
...
Fixes compiler warning
test-unicode.c:589:1: warning: ‘test_unicode_properties_lenient’ defined but not used
which didn't happen with autotools.
Reason it does with meson is that the setup for C was slightly wrong.
We would only add -DHAVE_CONFIG_H to cpp_args which is only valid when
compiling C++ code, but not plain C code, and many of these tests were
plain C.
Instead pass -DHAVE_CONFIG_H via add_project_arguments() and make sure
to set both c_args and cpp_args when building test executables.

using that makes sure we both fix and the timeout and don't need to change
