soc/intel/common/block/acpi: Add GPE1 blocks to ACPI FADT table

Use CONFIG_SOC_INTEL_COMMON_BLOCK_ACPI_GPE1 to enable GPE1 block. This
will include GPE1 blocks to FADT with their info.

BUG=362310295
TEST=boot to OS and check that FADT table include GPE1.
FADT should have:
GPE1 Block Address : 00001810
GPE1 Block Length : 18
GPE1 Base Offset : 80
