  [BOLT][DWARF] Update DW_AT_comp_dir/DW_AT_dwo_name for DWO TUs (#91486)

Type unit DIE generated by clang contains DW_AT_comp_dir/DW_AT_dwo_name.
This was added to clang to help LLDB to figure out where type unit come
from when accessing an entry in a .debug_names accelerator table and
type units in .dwp file.

When BOLT writes out .dwo files it changes the name of them. User can
also specify directory of where they can be written out. Added support
to BOLT to update those attributes.
