Modules: Do not implicitly add new functions via old Check Modules
The conversion of Check<Lang>CompilerFlag, SourceCompiles, and SourceRuns over to the new functions has the possibility of breaking projects that had functions with those existing names. To reduce the possibility of collisions we now have all the legacy code call functions that start with `cmake_`, and users will need to explicitly include the new modules to get the non-prefixed versions Fixes: #21359
