[Editor] Add the ability to create/update the structure tree when saving a pdf containing newly added annotations (bug 1845087)

Browse source 
When there is no tree, the tags for the new annotions are just put under the root element.
When there is a tree, we insert the new tags at the right place in using the value
of structTreeParentId (added in PR #16916).
