sw: implement protection of bookmarks and fields

SwPaM::HasReadonlySel() checks PROTECT_BOOKMARKS / PROTECT_FIELDS
setting and checks if bookmarks or fields are selected for deletion.

This should already be called by the UI code in all the right places,
for the other content protection features, and cause a dialog to pop
up.

What's not ideal about this is that it's impossible to delete a
character immediately before or after a point bookmark because that
would delete the point bookmark too.

The bookmark check is done by extracting a function out of
MarkManager::deleteMarks() so both will use the same logic.

The problem of DelContentIndex() duplicating that logic remains...

Apparently the status bar at the bottom already displays "read-only"
for such a selection.
