soc/intel/mtl: Add GPIOs for Meteor Lake SOC

Add definitions for the GPIO pins on Meteor Lake SoC,
as well as GPIO IRQ routing information and supporting ACPI ASL.

For now, add the following GPIO communities and GPIO groups:

Comm. 0: GPP_CPU, GPP_V, GPP_C
Comm. 1: GPP_A, GPP_E
Comm. 3: GPP_H, GPP_F, SPI0, VGPIO3
Comm. 4: GPP_S, JTAG
Comm. 5: GPP_B, GPP_D, VGPIO

BUG=b:224325352
TEST=util/abuild/abuild -p none -t google/rex -a -c max
