Subject: [PATCH] RC: Enable language after C, CXX, or Fortran is enabled
 (#15404)

The RC language is special in that it is automatically enabled
on Windows-based platforms when another primary language is
enabled.  Move enablement of RC from early in the enablement
of the other language to late.  This will allow it to use
information detected as part of enabling C, CXX, or Fortran.
