[llvm] [DebugInfo][ObjectYAML] Remove duplicate "Flags" field from LabelSym (PR #88194)

[via llvm-commits]

https://github.com/nikitalita created https://github.com/llvm/llvm-project/pull/88194

There was a duplicate flags field mistakenly left in LabelSym. [LabelSym only has one flags field](https://github.com/microsoft/microsoft-pdb/blob/805655a28bd8198004be2ac27e6e0290121a5e89/include/cvinfo.h#L3806
