x86/mce: Add an AMD severities-grading function

Add a severities function that caters to AMD processors. This allows us
to do some vendor-specific work within the function if necessary.

Also, introduce a vendor flag bitfield for vendor-specific settings. The
severities code uses this to define error scope based on the prescence
of the flags field.

This is based off of work by Boris Petkov.

Testing details:
Fam10h, Model 9h (Greyhound)
Fam15h: Models 0h-0fh (Orochi), 30h-3fh (Kaveri) and 60h-6fh (Carrizo),
Fam16h Model 00h-0fh (Kabini)

Boris:
Intel SNB
AMD K8 (JH-E0)
