include/qemu/lockable: Use _Generic instead of QEMU_GENERIC

This is both more and less complicated than our expansion
using __builtin_choose_expr and __builtin_types_compatible_p.

The expansion through QEMU_MAKE_LOCKABLE_ doesn't work because
we're not emumerating all of the types within the same _Generic,
which results in errors about unhandled cases.  We must also
handle void* explicitly, so that the NULL constant can be used.
