Update cmake files and wamr-test-suites to support collect code coverage (#1992)

Support collecting code coverage with wamr-test-suites script by using
lcov and genhtml tools, eg.:
  cd tests/wamr-test-suites
  ./test_wamr.sh -s spec -b -P -C

The default code coverage and html files are generated at:
  tests/wamr-test-suites/workspace/wamr.lcov
  tests/wamr-test-suites/workspace/wamr-lcov.zip

And update wamr-test-suites scripts to support testing GC spec cases to
avoid frequent synchronization conflicts between branch main and dev/gc.
