[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.
