[PATCH v3 2/6] efi/cper: Export cper_mem_err_unpack() for use by modules

The CXL driver plans to use cper_print_aer() for restricted CXL host (RCH)
logging. This is not currently possible if CXL is built as a loadable
module because cper_print_aer() depends on cper_mem_err_unpack() which
is not exported.

Export cper_mem_err_unpack() to enable cper_print_aer() usage in
CXL and other loadable modules.
