  -----------
  [AArch64][Build Attributes] Improve Parsing and Formatting (#126530)

- Removed assertion for duplicate values as adding them is valid.
- Fix parsing: reject strings for unknown tags, allow any value for
Tag_PAuth_Platform and Tag_PAuth_Schema.
- Print tags by using numbers with comments to reduce compiler-assembler
dependencies.
- Parsing error messages now only point to the symbol (^) instead of
printing it.
