Require CMAKE_<LANG>_COMPILER to be found as a full path All generators now support detection of the full path to the compiler, so require it to be so. This will allow CMake<LANG>Information.cmake and other logic to assume the full path to the compiler tool is available. The Makefile generators already rejected CMAKE_<LANG>_COMPILER values that did not name an existing compiler. Extend this error message to all generators, make it occur as early as possible, and improve the message with advice about how to set the compiler. If the full path to the compiler is not known, finish enabling languages with a fatal error so configuration does not continue. For now, allow the RC language compiler to not be a full path. Later we will need to detect the full path to "rc" under the VS IDE. Add a RunCMake.CompilerNotFound test to cover failure cases. Fix the RunCMake.CompilerChange test EmptyCompiler case to work when configuration does not continue past enable_language.

nmake/jom: Only warn about bad VS environment if compiler not found. nmake and jom generators no longer warn about missing INCLUDE/LIB environment variables unless the C/CXX compiler cannot be found. This is useful if the user does not want to use these generators with the Visual C++ compiler, or they do not want to enable any language.
