base: Use std::move() instead of Pass() for real movable types.

Some of our movable types have real move-constructors/assignment
operators now. We can use std::move() for these types instead of Pass().

There's still some move-only types that are implemented using an
"Rvalue" type emulation, so we have to keep Pass() for those still.
