Eliminate UnaryTypeTraitExpr

Remove UnaryTypeTraitExpr and switch all remaining type trait related handling
over to TypeTraitExpr.

The UTT/BTT/TT enum prefix and evaluation code is retained pending further
cleanup.

This is part of the ongoing work to unify type traits following the removal of
BinaryTypeTraitExpr in r197273.
