Mark certain plugins as unsupported on mobile

Current behaviour

At present, it's possible to install all plugins on mobile, even though many don't work. It's currently possible to mark plugins as desktop-only with the platforms manifest key. At present, however, no plugins do this (based on searching pluginData.json for the platforms key).

Expected behaviour

Plugins that don't work on mobile should be marked as such.

The existing manifestOverrides file could be used to add "platforms": ["desktop"] to some of the more popular plugins that only support desktop. Ideally, however, if a plugin author later adds "platforms": ["desktop","mobile"] to the manifest of a plugin that previously was desktop-only, it would be marked as compatible with mobile.

Here are a few options:

1. Add a manifestDefaults.json or similar file that provides default manifest values for different plugins.
2. Add plugin platforms to manifestOverrides.json and instruct plugin authors to open a pull request on the plugins repository when a plugin adds mobile support.
   • A sample diff for this can be found here: https://github.com/joplin/plugins/compare/master...personalizedrefrigerator:joplin-plugin-repo-fork:pr/mark-incompatible-plugins?expand=1
3. Make all plugins last published earlier than some date default to desktop-only, make newer plugins default to supporting both desktop and mobile.

Option 2 should be easiest to implement.
