This commit adds ops to vlapic structure, and add an *ops parameter to vlapic_reset().
At vlapic reset, the ops is set to the global apicv_ops, and may be assigned
to other ops later.

In current design, devicemodel passes VM UUID to create VMs and hypervisor
would check the UUID whether it is matched with the one in VM configurations.
Kata container would maintain few UUIDs to let ACRN launch the VM, so
hypervisor need to add these UUIDs in VM configurations for Kata running.
In the hypercall of hcall_get_platform_info(), hypervisor will report the
maximum Kata container number it will support. The patch will add a Kconfig
to indicate the maximum Kata container number that SOS could support.
In current stage, only one Kata container is supported by SOS on SDC scenario
so add one UUID for Kata container in SDC VM configuration. If we want to
support Kata on other scenarios in the future, we could follow the example
of this patch;

to the current vCPU, in this case, the IRR (for APICv base situation) or PIR
(for APICv advanced situation) and TMR for both cases could be accessed by more
