Updated OpenCore to 0.8.5 to add support for Ventura Developer Beta 9.
Disabled TRIM on boot to speed up boot, which also applies to VM disks with "discard" enabled (you can re-enable full disk trim on boot by setting SetApfsTrimTimeout
to -1
if you like).
Note that Ventura requires AVX2 support, so your host CPU needs to be Haswell or newer, and your CPU type set to Haswell in your VM config.
