arm: [MVE intrinsics] rework vuninitialized

Implement vuninitialized using the new MVE builtins framework.

This patch is a bit more intrusive than other similar patches because
the two vuninitialized variants use different signatures.

To handle this situation, the patch makes the inherent shape derive
from overloaded_base instead of nonoverloaded_base, and adds a new
parameter to add_unique_function so that we can choose between adding
only the nonoverloaded version, only the overloaded ones, or both (the
default).

The patch introduces pop_and_resolve_to, which pops an argument (the
only one in this case), and calls resolve_to, like many other shapes:
this is because the overloaded version takes an argument (used to
resolve which nonoverloaded version to call), which is not present in
the nonoverloaded version prototype.
