Modules: Introduce CMAKE_EFFECTIVE_SYSTEM_NAME to lookup compiler info

Create a `CMAKE_EFFECTIVE_SYSTEM_NAME` variable to use for looking
up compiler information modules instead of using `CMAKE_SYSTEM_NAME`
directly.  This will allow multiple platforms to share the same set
of compiler information modules without spelling out all of them.
