[ARM][MVE] Make VPT invalid for tail predication

We've been marking VPT incompatible instructions as invalid for tail
predication too, though this may not strictly be true. VPT are
incompatible and, unless its the first predicate def in a loop,
they shouldn't be compatible for tail predication either.
