  [BOLT][DWARF] Fix handling .debug_str_offsets for type units (#75522)

There was an assumpiton that TUs and CUs share .debug_str_offsets
contribution. For ThinLTO builds it is not the case. Changed so that we
parse contributions for TUs also, and did some refactoring so that we
don't re-parse contributions that were not modified.
