[TableGen] Avoid a couple vector copies in ExpandHwModeBasedTypes.

Use vector::swap instead of copying to a local vector and clearing
the original. We can just swap into the just created local vector
instead which will move the pointers and not the data.

Use std::move in another place to avoid a copy.
