Improve preference renderer linking

[msujew]

What it does

Fixes a few minor issues which should massively reduce the amount of Linked preference "<id>" not found. warnings printed to the console:

1. Don't use a link to window.titleBarStyle when not in Electron mode (the linked preference does only exist in Electron).
2. Use editor.cursorSurroundingLines instead of cursorSurroundingLines as a link.
3. Some extensions sometimes link commands in the preferences. We now also use the CommandRegistry to figure out the name of a linked command.
4. Caches the IDs of the tree nodes of every preference so that we can later find the tree ID again for any preference ID. That way, we don't have to recompute the ID to figure out the real name of a preference (and potentially do that incorrectly).

How to test

1. Open the application.
2. Open the settings/preference view
3. Assert that there are much fewer warnings in the console.
4. Assert that all links to other preferences are correctly rendered and actually make you jump to that preference.
