not that you want to change these as part of upstream, but for these simple data
objects where all members are final I think it is fine to just make the member
variables public (drop the m prefix) and get rid of these accessors.

Seems like we should be checking that mClearBrowsingDataListener is null here
otherwise if you had two callers it could never notify the previous one.

And to me it really seems like the listener should be associated with the
request and not saved as a member variable at all.

But I digress and this is outside of the scope of this change.
