This commit provides APEI arch-specific bits for aarch64
Meanwhile,
(1)add a new subfunction "hest_ia32_init" for
"acpi_disable_cmcff" which is used by IA-32 Architecture
Corrected Machine Check (CMC).
(2)move HEST type (ACPI_HEST_TYPE_IA32_CORRECTED_CHECK) checking to
a generic place.
(3)select HAVE_ACPI_APEI when EFI and ACPI is set on ARM64,
because arch_apei_get_mem_attribute is using efi_mem_attributes on ARM64.
