Fix build warnings noreturn M2RTS and fix calls to RegisterModule [PR108956]

Fix build warnings noreturn M2RTS and fix calls to RegisterModule [PR108956]

mc needs a fix to optionally suppress the generation of the noreturn
attribute when building M2RTS.  All the hand built C++ modules calling
RegisterModule must supply the library name.  These changes require
the boot strap tools mc and pge to be rebuilt.
