Fixes three issues with MWCC class unique ID normalization for symbol pairing:
$132966and$55068would not have been recognized as the same)The third issue is difficult to fix on the mangled name, as the length of the name is included within the symbol, so I switched it to normalize and compare on the demangled version of the name, which does not include these lengths. This is inconsistent with how the mangled name is usually used for comparisons in all other cases in objdiff. However, it's a simpler solution that trying to fix the mangled name lengths, as that requires duplicating a large chunk of demangler logic within objdiff (#410).
Only downside I'm aware of here is that if the demangler ever failed to work on one of these symbols for some reason, the normalization would also not happen either then.
