interrupt_controller: gicv3: add support for LPIs

The LPI (Locality-specific Peripheral Interrupts) are edge-triggered
message-based interrupts that can use an Interrupt Translation
Service (ITS) to route an interrupt to a specific Redistributor and
connected PE.

This implement the necessary LPI support when an ITS is enabled.

The LPI states are stored in memory-backed tables.
