[glib] update to <2.80.3>

[JonLiu1993]

Fixes #39531

1. Update glib to the latest version 2.80.3
2. Add python package packaging module required in meson.build
3. Add tools of gi-compile-repository, gi-decompile-typelib and gi-inspect-typeli

All features are tested successfully in the x64-linux triplet.

• Changes comply with the maintainer guide.
• SHA512s are updated for each updated download.
• The "supports" clause reflects platforms that may be fixed by this new version.
• Any fixed CI baseline entries are removed from that file.
• Any patches that are no longer applied are deleted from the port's directory.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is added to each modified port's versions file.

The meson options have been renamed, so you need to adapt the invokation of vcpkg_configure_meson. There's some additional changes, too, maybe you can merge this PR / Issue onto #37473 / #37286 which does most of the heavy lifting involved in the ABI and build system adaptions required to upgrade glib from the 2.7x series .
