Avoid if() quoted auto-dereference when checking for "MSVC" When testing CMAKE_<LANG>_COMPILER_ID values against "MSVC", do not allow the definition of the "MSVC" variable to be expanded.

Features: Ensure appropriate return value from feature test macros. GNU-CXX already has complex logic and sets the _result to 0 before tests which may set it to something else. Change the other modules to be consistent with that.
