Delete `wrap-global-context` pass. (#4114)

* Delete `wrap-global-context` pass.

The pass was added for the metal backend without realizing that the existing `explicit-global-context` does 99% of the job. Instead of duplicating the logic in a different pass for metal, we extend same explicit-global-context pass to work for metal.

* Fix build.
