meson: Fix compile failures on macOS in harfbuzz and pango

These patches are taken from upstream, and they fix compile failures
with latest clang. These can be dropped when upgrading these wraps.

This is currently causing a warning because we do not require the
version of meson that ships with this feature: 0.63.0. The version has
not been bumped because older Meson versions gracefully ignore the
wrap field, this fix is optional and only needed on macOS, and 0.63.0
is a very new release with a bug that partially breaks this feature:

https://github.com/mesonbuild/meson/pull/10602

We can consider bumping the requirement once 0.63.1 is released.

Also switch from git to tarballs, no reason to use git here anymore.
