[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

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.

Fixes compiler warning
test-unicode.c:589:1: warning: ‘test_unicode_properties_lenient’ defined but not used

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.

[subset] Avoid incorrectly dropping cmap for NotoColorEmoji.ttf
...
NotoColorEmoji.ttf uses two cmap subtables
Format 14 | Platform ID 0 | Platform Encoding ID 5
Format 12 | Platform ID 3 | Platform Encoding ID 10
This combination results in the cmap table being dropped during subsetting despite being valid/required.

[subset] Fix namerecord ordering
...
This will fix inconsistency with fontTools.
Also according to the spec, namerecords must be sorted
first by platform ID, then by platform-specific ID,
then by language ID, and then by name ID.

[subset] CMAP table subsetting fix
...
Not all codepoints smaller than 0xFFFF go to cmap4 table.
Only subset codepoints existing in each table.
This will also make harfbuzz consistent with fontTools' behavior
