[globalisel][legalizer] Add AtomicOrdering to LegalityQuery and use it in AArch64

Now that we have the ability to legalize based on MMO's. Add support for
legalizing based on AtomicOrdering and use it to correct the legalization
of the atomic instructions.

Also extend all() to be a variadic template as this ruleset now requires
3 and 4 argument versions.
