[dwarfdump] Rename Brief to Verbose in DIDumpOptions 

This patches renames "brief" to "verbose" in de DIDumpOptions and
inverts the logic to match the new behavior where brief is the default.
Changing the default value uncovered some bugs related to the
DIDumpOptions not being propagated and have been fixed as well.
