PR modula2/114565 progress trace would be useful to isolate ICE for users

This patch introduces the internal option -fm2-debug-trace= which can
be given a comma separated list of filter terms.  Currently it allows:
all,line,token,quad.  The patch allows users to trace the progress of
cc1gm2 so that source which causes an ICE can be reduced.  Once
PR113836 is complete it is expected that the trace information will be
written to file.
