Enable x2APIC controller support on x86 and OVA (#4342)

Browse Source 
This might be required for some modern Intel processors (Meteor Lake and newer)
which fail to boot Linux kernel without x2APIC controller when some features
(e.g. VT-d or x2APIC itself) are enabled in the BIOS.

Enable it also for OVA, as it can be emulated in virtual machines, even when
the host CPU does not support it.

Fixes #4337, fixes #4144, fixes #4345
