[roll] Roll fuchsia [kernel][gicv3] Support LPI and ITS MSI-X

On ARM64 platforms with a GICv3 Interrupt Translation Service (such as
GCE t2a-standard-4), PCI devices such as NVMe and Virtio use MSI-X
interrupts translated by the GICv3 ITS into Locality-specific
Peripheral Interrupts (LPIs, INTID >= 8192). Previously, Zircon's GICv3
driver returned ZX_ERR_NOT_SUPPORTED for all MSI operations and masked
ICC_IAR1_EL1 with 0x3ff, preventing MSI-X allocation and LPI dispatch.

Update the GICv3 driver to support Redistributor LPIs and ITS-backed
MSI/MSI-X interrupts:

1. Add GICR LPI (GICR_PROPBASER, GICR_PENDBASER, GICR_INVLPIR,
   GICR_INVALLR, GICR_SYNCR) and GICv3 ITS (GITS_*) register
   definitions in arm_gicv3_regs.h.
2. Read the ITS physical base address passed by the bootloader in
   zbi_dcfg_arm_gic_v3_driver_t::its_phys, with a fallback to
   mmio_phys + 0x80000 when gicr_offset >= 0xa0000.
3. Allocate and program the shared 64-KiB LPI configuration table and
   per-CPU 64-KiB LPI pending tables with Shareability WARL handling,
   and enable GICR_CTLR_ENABLE_LPIS on each CPU.
4. Probe and configure GITS_BASER device and collection tables (handling
   64K/16K/4K page size and Shareability WARL fields) and the 64-KiB
   GITS_CBASER command queue, enable GITS_CTLR, map Collection 0 to
   CPU 0 (MAPC), and map PCI bus 0 device IDs (MAPD) sized according to
   GITS_TYPER.ITT_entry_size.
5. Implement gic_msi_is_supported, gic_msi_supports_masking,
   gic_msi_mask_unmask, gic_msi_alloc_block, gic_msi_free_block, and
   gic_msi_register_handler targeting GITS_TRANSLATER and issuing
   batched MAPTI, INV, and SYNC commands.
6. Update gic_handle_irq to mask ICC_IAR1_EL1 with 0xffffff (24-bit
   INTID) and dispatch LPIs (INTID >= 8192).
