hw/intc/arm_gicv3_its: Implement VINVALL

The VINVALL command should cause any cached information in the
ITS or redistributor for the specified vCPU to be dropped or
otherwise made consistent with the in-memory LPI configuration
tables.

Here we implement the command and table parsing, leaving the
redistributor part as a stub for the moment, as usual.
