  [BOLT][DWARF] Add support for .debug_names (#81062)

DWARF5 spec supports the .debug_names acceleration table. This is the
formalized version of combination of gdb-index/pubnames/types. Added
implementation of it to BOLT. It supports both monolothic and split
dwarf, with and without Type Units. It does not include parent indices.
This will be in followup PR. Unlike LLVM output this will put all the
CUs and TUs into one Module.
