meson: Don't list libraries private dependencies in pc files

pkg-config files for mutter are generated using *_pkg_deps as requires, but
programs linked with libmutter doesn't need most of these private dependencies
which are only needed for building and linking mutter and its subprojects.

So list packages needed only by mutter itself inside *_pkg_private_deps and
don't expose such packages to pkg-config, but only use them at build time.
