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.
