Rename PAL_CMAKE_* CLR_CMAKE_* (#1984)

* Rename PAL_CMAKE_* CLR_CMAKE_*

Remove separatation between CLR_CMAKE and PAL_CMAKE defines

Revise PAL_CMAKE_PLATFORM* defines to use CLR_CMAKE_HOST* defines

Revise other PAL_CMAKE_* defines to use CLR_CMAKE_* equivalents.

Remove redundant compiler configuration
