Add QualifierAlignment to Clang Format Config (facebook#44098)

Summary:
Pull Request resolved: facebook#44098

This sets `QualiferAlignment` so that code is automatically formatted to west const.

I did a pass at this before, but now that we are on new Clang Format, we can enforce it automatically, and I think a couple more cases not previously changed now are.
