Enhance build configuration to support optional gc

There will be two sets of binaries for iwasm and wamrc.
One set without a suffix indicates there is no GC support.
Another set with the suffixes "-gc" and "-gc-eh" includes GC support.
Users cannot disable GC through command line options; they need to
choose the appropriate set to use.
