cmake: fix various misuses of MESSAGE() The MESSAGE() function expects as first argument the message type, e.g. STATUS or FATAL_ERROR. In some places, we were misusing this to either not provide any type, which would then erroneously print the message to standard error, or to use FATAL instead of FATAL_ERROR. Fix all of these instances. Also, remove some MESSAGE invocations that are obvious leftovers from debugging the build system.
