[ARM][CGP] Fix scalar condition selects for MVE

The arm backend does not handle select/select_cc on vectors with scalar
conditions, preferring to expand them in codegenprepare instead. This
usually works except when optimizing for size, where the optsize check
would end up overruling the backend isSelectSupported check.

We could handle the selects in ISel too, but this seems like smaller
code than trying to splat the condition to all lanes.
