Introduce support for target_clones attribute ( #3280 )
...
This requires GLIBC 2.23+, plus either gcc 6+ or clang 14+.
- Provides build-time feature detection
- Use with (un)premultiply for ~10% perf gain on AVX CPUs
- Slightly increases binary size, so best to use sparingly

Cleanup gettext handling ( #2695 )
...
Use GLib's i18n support instead of copying and pasting that
logic into its own header. This deprecates the vips/intl.h
header in favour of glib/gi18n.h.
