By reusing `cgif->palette_rgb`, this ensures that `pLocalPalette`

CI: upgrade runner to Ubuntu 22.04 (#2850) 
* 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.

Minor cleanups (#2857) 
- Remove `HAVE_LCMS` definition in favor of `HAVE_LCMS2`.
- Remove `HAVE_WINDOWS_H` definition in favor of `G_OS_WIN32`.
- 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.

Prefer to use flags |= everywhere (#2854) 
Use the bitwise OR assignment operator to ensure that derived
classes does not overwrite the flags from the base class. Also,
move the flags from `openslideload_source` to its base class.

a9bfd508f5 revise cgifsave checksum 
We were calling it a sum and looking for a change threshold, but really
it's only useful as a checksum and does not have a magnitude. Revise
comments and variable names to reflect this.
