ACPI S3: Remove HIGH_MEMORY_SAVE where possible
Add implementation to use actual requirements of ramstage size for S3 resume backup in CBMEM. The backup covers complete pages of 4 KiB. Only the required amount of low memory is backed up when ACPI_TINY_LOWMEM_BACKUP is selected for the platform. Enable this option for AGESA and binaryPI, other platforms (without RELOCATABLE_RAMSTAGE) currently keep their romstage ramstack in low memory for s3 resume path.
