[ELF] Change --call-graph-profile-sort to accept an argument

Change the FF form --call-graph-profile-sort to --call-graph-profile-sort={none,hfsort}.
This will be extended to support llvm/lib/Transforms/Utils/CodeLayout.cpp.

--call-graph-profile-sort is not used in the wild but
--no-call-graph-profile-sort is (Chromium). Make --no-call-graph-profile-sort an
alias for --call-graph-profile-sort=none.
