[cxxmodules] Allow ROOT_ prefix module to be implicitly build by rootcling

[yamaguchi1024]

Previously, [system] was used to mark modules which were supporsed be implicitly built by rootcling for runtime modules. This was a workaround, and it was causing SourceLocation error in cxxmodules as it is also using the same modulemap.

To remove the workaround, we are introducing a new convention that modules start with ROOT_ is treated as "ROOT system modules", which can be build implicitly.
