Ebrahim Byagowi 6b75a30a73 [draw/test] Swap a freetype test case with a simpler one
As CI failure, apparently the my local freetype and CI one have different
result so let's switch the case with a simpler one just to test quadratic command
is emitted correctly.

Ebrahim Byagowi d4588204e5 [draw/glyf] Emit empty contours
This makes it actually match freetype behaviour even though rasterizer
should filter such contours specially for stroking.

See https://github.com/harfbuzz/harfbuzz/pull/3411#discussion_r802283827 for the context.

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.

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.

Fixes #2338

Tim-Philipp Müller a3892be701 [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.

They aren't contributing to rendering and making issue for stroking, let's skip them
ourselves as Skia does also https://skia-review.googlesource.com/c/skia/+/268166

They are useful for extracting extents and so which that functionality won't be effected by this change.
