      .SMBIOS 3.0 uses `auto` type for entry point by default

      This enhancement adds support for System Management BIOS (SMBIOS) 3.0 entry point and enables it on pc-q35-rhel9.4.0 and newer machines. SMBIOS only supports on latest `q35` machines with `auto` type entry point by default.

      This bug was initially created as a copy of Bug #1904267

      I am copying this bug because:
      Once we support SMBIOS 3.0, we want it to be enabled automatically when necessary. This can be done in two different ways:

      • Automatically enable SMBIOS 3.0 when the tables can't fit in a SMBIOS 2.1 entry point. This keeps gust ABI compatibility and doesn't require a new machine type).
      • Enable SMBIOS 3.0 by default on all VMs. This changes guest ABI and can be done only on new machine types.

      A VM with more than ~720 VCPUs can hit the 65535 bytes limit on SMBIOS tables. edk2, however, supports SMBIOS 3.0 Entry Points.

      We need to support SMBIOS 3.0 entry points on Q35, probably through a new command line option.
