These follow GObject conventions, using `G_TYPE_CHECK_INSTANCE_CAST` to
cast to the given type, and potentially performing some runtime checks
of the type instance’s `GType` too.

This means they’re now using the `GType` type system rather than the old
`GIInfoType` type system. Given the preceding few commits, these two
systems should now be equivalent.
This makes the type handling more conventional and hence a bit simpler
for people to use if they have experience with GObject.

This makes `GIBaseInfo` and derived types more consistent with GObject
convention, and thus a bit more comfortable to use.

Review and update the documentation, making sure it’s complete,
formatted in gi-docgen format, and has all appropriate GIR annotations
and `Since:` lines.

This adds more type safety to libgirepository, and allows
differentiating the `GIBaseInfo` derived types using the type system.
Two new derived types had to be added (previously they were just a
collection of helper methods which worked directly on a `GIBaseInfo` and
didn’t check types): `GICallbackInfo` and `GIUnresolvedInfo`.
Further cleanups and refactoring might be needed on this, but the core
of libgirepository now uses `GTypeInstance` and appears to still work
(it’s difficult to be entirely sure because there are no unit tests
yet).
