Also, print out the name of the matching Error Structure Type.

Only print the GUID for unknown types.

GUIDs taken from UEFI 2.7 section N.2.4.2.1 IA32/X64 Processor Error
Information Structure.

f9e1bdb9f3 efi: Decode IA32/X64 Processor Error Section 
Recognize the IA32/X64 Processor Error Section.

Do the section decoding in a new "cper-x86.c" file and add this to the
Makefile depending on a new "UEFI_CPER_X86" config option.

Print the Local APIC ID and CPUID info from the Processor Error Record.

The "Processor Error Info" and "Processor Context" fields will be
decoded in following patches.

Based on UEFI 2.7 Table 252. Processor Error Record.
