x86/acpi: Add APEI definitions

Browse Source 
Add ACPI Platform Error Interfaces definitions that will be used
for building a BERT table region in a subsequent patch.  Two tables
are defined:  the Generic Error Status Block, Generic Error Data
Entry.

For reference, see the ACPI specification 6.2-A tables 381 and 382.

BUG=b:65446699
TEST=inspect BERT region, and dmesg, on full patch stack.  Use test
     data plus a failing Grunt system.
