Android,Desktop: Plugin API: Fix unable to require @codemirror/search

[personalizedrefrigerator]

Summary

Allows requiring the Joplin built-in version of @codemirror/search from the plugin API. This allows plugins to toggle CodeMirror search, get the current search query, and move between search matches.

Testing

1. Apply the following diff:

2. Add the codemirror6 demo plugin.
3. Search for something not containing the letter a that has multiple matches with ctrl-f (cmd-f on Mac?)
4. Click on the main editor and press a. Verify that this moves to the next match.
