* CI: upgrade runner to Ubuntu 22.04
- Compile with GCC 11 and Clang 14.
- Remove redundant PPAs.
- Use system provided Meson.
- Update LeakSanitizer suppressions.
* CI: ensure `VIPS_BLOCK_UNTRUSTED` is tested
`magicksave` cannot be used for testing when building with
`-Dmodules=enabled` (default), since that would require the
loadable modules to be installed first.

- Remove stray `vips_text_get_type` in `conversion.c`.
- Remove duplicated `unistd.h` include.
- Remove redundant `strcasecmp` definition, we use `g_ascii_strcasecmp` everywhere.
- Remove unnecessary header checks in `configure.ac` and `meson.build`.
- Ensure `unistd.h` include is guarded with `HAVE_UNISTD_H`.
- Fail early when `-Dfontconfig=enabled` and `pangoft2` is not found.
