hw/intc/arm_gicv3_its: Implement GITS_BASER2 for GICv4
The GICv4 defines a new in-guest-memory table for the ITS: this is the vPE table. Implement the new GITS_BASER2 register which the guest uses to tell the ITS where the vPE table is located, including the decode of the register fields into the TableDesc structure which we do for the GITS_BASER<n> when the guest enables the ITS. We guard provision of the new register with the its_feature_virtual() function, which does a check of the GITS_TYPER.Virtual bit which indicates presence of ITS support for virtual LPIs. Since this bit is currently always zero, GICv4-specific features will not be accessible to the guest yet.
