For normal compilation, use .typelib files rather than .gir XML files. This is much faster. Rather than using libgirepository, which would try to actually load the libraries, we use a custom parser. The language server will still read XML because it needs to access documentation, which is not in the typelib, but that's generally fine because it's a long lived process and only has to do that once.
