Enable the Serialization/restrict-swiftmodule-to-revision on Windows.
This test was unnecessarily disabled on Windows due to the use of
environment variables which can be accommodated by using the `env`
command.
Introduce a new loading restriction that is more strict than the serialization
version check on swiftmodules. Tagged compilers will only load
library-evolution enabled swiftmodules that are produced by a compiler with the
exact same revision id. This will be more reliable in production
environments than using the serialization version which we forgot to
update from time to time. This shouldn't affect development compilers that
will still load any module with a compatible serialization version.
