runtime(filetype): Modula-2 files with priority not detected (#14055)

Problem:  Modula-2 files with a specified priority are not detected.
Solution: Match the priority syntax in module header lines when
          performing heuristic content detection.

Disable the :defcompile debug line.  This was accidentally left enabled
in commit 68a8947.
