[BOLT][DWARF] Add support for transitive DW_AT_name/DW_AT_linkage_name resolution for DW_AT_name/DW_AT_linkage_name. (#119493)
This fix handles a case where a DIE that does not have
DW_AT_name/DW_AT_linkage_name, but has a reference to another DIE using
DW_AT_abstract_origin/DW_AT_specification. It also fixes a bug where
there are cross CU references for those attributes. Previously it would
use a DWARF Unit of a DIE which was being processed The
warf5-debug-names-cross-cu.s test just happened to work because how it
was constructed where string section was shared by both DWARF Units.
To resolve DW_AT_name/DW_AT_linkage_name this patch iterates over
references until it either reaches the final DIE or finds both of those
names.
