Hi All.

This patch aims to add GICv3 support to the New VGIC. It adds support for
the GICv3 distributor, redistributor, sysreg and ITS interfaces. This will
allow Xen to emulate level-triggered interrupts with GICVb3 and will make
the NEW_VGIC more complete and usable.

The bulk of the code is taken from the Linux Kernel v6.0 and adapted to the
existing Xen codebase.

For the NEW_VGIC config the !GIC_V3 dependency is removed.
For the HAS_ITS config the deprecated flag is removed and NEW_VGIC dependency
is added.

Original non-ported changes are:
- Moving the GICv3 distributor base to fix the new_vgic's intid calculation.
- Moving the get/put irq to a wider scope to properly integrate the ITS.
