[llvm] [DWARFLinkerParallel] Fix member initializer order (PR #81179)

[Fangrui Song via llvm-commits]

https://github.com/MaskRay created https://github.com/llvm/llvm-project/pull/81179

DWARFLinkerImpl::DWARFLinkerImpl initializes
DebugStrStrings/DebugLineStrStrings/CommonSections using GlobalData
but GlobalData is initialized after the three members.
Move GlobalData before.

Fix #81110
