Re-add content search type

[tobiasKaminsky]

Depends on nextcloud/android-library#319

❗ Stalled by nextcloud/android-library#319 ❗
Should be based upon photoSearchLimit branch.

This is completely new fragment and I believe we could greatly benefit from using ViewModel here. View models greatly improve testability.

@ezaquarii I messed something up. I wanted to split up #2250 so that #2250 does not contain any "content search type".
Now it seems that both PRs have the same changes to master and so your comments need to be in #2250.
I'll check them and change them in #2250 and after that try to rebase this PR to be ontop of #2250, also changing the base branch here in github.

While this is a new fragment, it is "only" a subset of OCFileListFragemnt, which is a subclass of ExtendedListFragment.

Indeed, we should change this, but please not in this PR.

[tobiasKaminsky]

All further discussion should go in #2250 as this PR will be based on it.
