Subject: [PATCH 1/2] [GeckoView] Add
 `web-digital_signature_properties_manager` import map (PR 21247 follow-up)

Currently the GeckoView development viewer, i.e. http://localhost:8888/web/viewer-geckoview.html, is completely broken with the following error:
```
Uncaught TypeError: The specifier “web-digital_signature_properties_manager” was a bare specifier, but was not remapped to anything. Relative module specifiers must start with “./”, “../” or “/”. app.js:97:44
```

Subject: [PATCH 2/2] Remove unnecessary class-field resetting in
 `SignaturePropertiesManager.prototype.setDocument` (PR 21247 follow-up)

This corresponds to the initial values of these fields, and they were *already* reset when a (previous) PDF document was closed.
