Scripting clients (like the LOK API) had a way to get all custom
properties where the name matches a certain prefix, but setting such
properties was not possible.
.uno:SetDocumentProperties can already show a dialog to edit properties
interactively and had a parameter to set some properties in a
non-interactive way, but there doesn't seem to be a way to influence
custom properties there without using the internal API.
Fix the problem by adding a new UpdatedProperties parameter that allows
removing all old custom properties matching the prefix and adding new
ones with a single UNO command dispatch.
This is meant to be the write side of the reading commit
5e8f6dcb8c (sw lok,
.uno:SetDocumentProperties: expose value of custom document properties,
2022-11-29).
