SharonXSharon 79cc728b77 [lld][macho] Strip .__uniq. and .llvm. hashes in -order_file (#140670) ...

```
/// Symbols can be appended with "(.__uniq.xxxx)?.llvm.yyyy" where "xxxx" and
/// "yyyy" are numbers that could change between builds. We need to use the root
/// symbol name before this suffix so these symbols can be matched with profiles
/// which may have different suffixes.
```
Just like what we are doing in BP,
https://github.com/llvm/llvm-project/blob/main/lld/MachO/BPSectionOrderer.cpp#L127

the patch removes the suffixes when parsing the order file and getting
the symbol priority to have a better symbol match.
