x86: EDAC: carve out AMD MCE decoding logic
This converts the MCE decoding logic into a standalone config option which can be built-in or a module, the first one being the default for MCEs happening early on in the boot process. This, beyond being separated in a cleaner way, also saves RAM by making the decoding logic modular.
