efi/cper, cxl: Decode CXL Protocol Error Section
Add support for decoding CXL Protocol Error Section as defined in UEFI 2.10
Section N.2.13.
Do the section decoding in a new cper_cxl.c file. This new file will be
used in the future for more CXL CPERs decode support. Add this to the
existing UEFI_CPER config.
