[llvm-dwarfdump] Make --verify for .debug_names multithreaded. (#127281)
This PR makes verification of .debug_names acceleration table
multithreaded. In local testing it improves verification of clang
.debug_names from four minutes to under a minute.
This PR relies on a current mechanism of extracting DIEs into a vector. 
Future improvements can include creating API to extract one DIE at a
time, or grouping Entires into buckets by CUs and extracting before
parallel step.
