Update for rename from MSVCRT to CRT (pvieito#29)

The `CRT` module is identical to `MSVCRT` except it does not expose the
`visualc` module.  The `MSVCRT` module has been removed to drop the
explicit dependency on the `visualc` module.

Bump the CI to the 11/04 snapshot.  Bump the swift-argument-parser
dependency for the Windows changes.
