support/testing/tests/fs/test_iso9660.py: add support to test using EFI BIOS

The ISO9660 tests are only testing BIOS Legacy.
Add support to test an ISO9660 image based on EFI BIOS.
Add support to test an ISO9660 hybrid image based on Legacy and EFI BIOS.
Add dedicated Grub2 builtin config for the EFI compatible cases.
