UefiCpuPkg/CpuExceptionHandler: Add missing comma to exception name array

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3373

An update to expand the mExceptionNameStr array failed to add a comma
after original last entry, therefore causing the #CP name to have extra
incorrect characters and the remaining entries to be indexed incorrectly
(off by 1).

Add a comma after the "#CP" entry to resolve this issue.
