cmd/compile: add coverage fixup mode
Adds a -coveragecfg=<configfile> command line option to the compiler
to help support a cooperative "tool and compiler" mode for coverage
instrumentation. In this mode the cmd/cover tool generates most of the
counter instrumentation via source-to-source rewriting, but the
compiler fixes up the result if passed the "-coveragecfg" option. The
fixups include:
- reclassifying counter variables (special storage class)
- marking meta-data variables are read-only
- adding in an init call to do registation
Updates #51430.
