We don't want or need any LOKClipboard on iOS

Try to make the code more like in the co-2021 branch, where copy/paste
between Collabora Office and other iOS apps currently works again, in
both directions, both for text and images. Sadly something is broken
or missing either here in core or in online as it doesn't fully work
in a Collabora Office based on the master branch of core, even after
this commit, though.

We use only the system clipboard on iOS. (It is actually called the
"pasteboard" in Apple's operating systems.) The code to interface with
the system clipboard is in vcl. It has worked fine to copy and paste
between the Collabora Office iOS app and other iOS apps without any
LOKClipboard being involved. If LOKClipboard is used it doesn't work
at all.
