hw/intc/arm_gicv3_its: Implement VINVALL

Browse source 
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.
