sw lok: expose name of bookmark under cursor

It was possible to get the names of all bookmarks, but you could not get
the name of the (innermost) bookmark under the current cursor.

Getting the name of the current bookmark is useful for Zotero: if we
already have a citation and want to insert one more, then we should turn
the current citation into a citation cluster.

Fix the problem by adding an API similar to what commit
bb20dee2ef1b0804065e1cda2c834d257fdd90ed (sw lok: expose field type &
command of fieldmark under cursor, 2023-01-05) did, but here we deal
with bookmarks, not fieldmarks.

Handle the actual bookmark lookup in MarkManager, such functionality
looks useful outside LOK as well.

(cherry picked from commit 4bcb66ec7b417fbe113267f2615e78fe47eb55ca)
