tdf#129328 Try to make Copy/Paste work sanely in the iOS app again

We don't want any of the stuff in loleaflet/src/map/Clipboard.js to be
involved at all. On iOS we have an interface to the system clipboard
in core. Just use that. No need to keep any local cached clipboard in
the Javascript. No "download" involved. Just let .uno:Cut etc do their
job. Keep the _clip attribute property of the L.Map object undefined
on iOS, and check if before trying to use it.

As such I couldn't exactly reproduce the problem in the bug report,
but hopefully this works.
