905f654b - [ELF] Replace getThreadIndex with explicit shards in RelocScan. NFC (#208959)

[ELF] Replace getThreadIndex with explicit shards in RelocScan. NFC (#208959) Parallel relocation scanning (https://reviews.llvm.org/D133003) appends dynamic relocations to `relocsVec[parallel::getThreadIndex()]`. `getThreadIndex` returns -1u on main, which is a known hazard. Instead, run one scan task per worker via `parallelFor`, with tasks claiming object files off a shared counter, and pass the task index through scanSection/RelocScan as the relocsVec shard.
