Li Fei1 6077152c4b hv: vlapic: extend vlapic_x2apic_pt_icr_access to support more destination mode
Now guest would use `Destination Shorthand` to broadcast IPIs if there're more
than one destination. However, it is not supported when the guest is in LAPIC
passthru situation, and all active VCPUs are working in X2APIC mode. As a result,
the guest would not work properly since this kind broadcast IPIs was ignored
by ACRN. What's worse, ACRN Hypervisor would inject GP to the guest in this case.

This patch extend vlapic_x2apic_pt_icr_access to support more destination modes
(both `Physical` and `Logical`) and destination shorthand (`No Shorthand`, `Self`,
`All Including Self` and `All Excluding Self`).

ACRN Hypervisor
###############

The open source `Project ACRN`_ defines a device hypervisor reference stack and
an architecture for running multiple software subsystems, managed securely, on
a consolidated system by means of a virtual machine manager. It also defines a
reference framework implementation for virtual device emulation, called the
"ACRN Device Model".

The ACRN Hypervisor is a Type 1 reference hypervisor stack, running directly on
the bare-metal hardware, and is suitable for a variety of IoT and embedded
device solutions. The ACRN hypervisor addresses the gap that currently exists
between datacenter hypervisors, and hard partitioning hypervisors. The ACRN
hypervisor architecture partitions the system into different functional
domains, with carefully selected guest OS sharing optimizations for IoT and
embedded devices.

You can find out more about Project ACRN on the `Project ACRN documentation`_
website.
