Extract metatype information as part of library finalization

Make qt_finalize_target call qt6_extract_metatypes() on any library
targets if the finalization is deferred and the target uses automoc.

This makes sure the metatype information is always available when
necessary (e.g. in QML's foreign types setting).

[ChangeLog][CMake][Important Behavior Changes] With CMake 3.19 or later
qt_extract_metatypes() is automatically called during target
finalization for libraries that use automoc now. This has no
effect if you've already manually called qt_extract_metatypes() before,
but it does make sure that the metatypes are also generated if you
haven't.
