find-unneeded-includes: Avoid proposing o3tl fw declaration

This does not really work: even when it seems to, it compiles only
because of transitive includes

- Filter o3tl/typed_flags_set.hxx in f-u-u
- Remove already added fw declarations from hxx files and
  include full header just in case
- Remove now unnecessary blacklist entries
