DW_TAG_atomic_type was already included in Dwarf.defs and emitted correctly, however Verifier didn't recognize it as valid. Thus we introduce the following changes:

- Make DW_TAG_atomic_type valid tag for IR and DWARF
- Add it to related docs
- Add it to CodeView debug as valid tag for derived types
- Add DebugInfo test
