 Fix: #12084 deprecate old profiling flags

 Change help message so it doesn't specify -auto-all.
 Make old profiling flags deprecated as they are no longer
 documented.
 Update Makefile and documentation accordingly.
 Update release notes for ghc 8.2

 Test Plan:
 ./verify; `ghc --help` shouldn't specify the -auto-all
 flag. Furthermore `ghc -fprof -auto-all` should emit a warning
