Add Support for Importing Shared Resource Files to Multiple Languages

[metrixsam]

Use Cases

The ability to select multiple languages and purposes for the same imported resource file can be extremely useful and save redundant storage space. For example, it would eliminate the need to import the same multilingual model repeatedly for individual languages, thus opening the gates for possibilities like intelligent language detection when speaking or typing.

Proposal

Solution:
This feature can be implemented through four simple steps:

1. Altering the way of handling metadata for different languages to enable using shared resources.
2. Altering the interface of selecting the target language for the imported resource file shown below to allow selecting multiple target languages and move the left pointing arrows to one common "next" (or arrow) button at the bottom of the screen.
   
3. Adding a third button to resource selection pop up interfaces similar to the one below to allow using an existing resource.
   
4. Adding another option to this menu to manage imported resource files and control whether they are shared or not, their respective language(s), etc.
   

Notes:
A similar feature was already implemented in the voiceinput project. The app automatically detects and uses the same downloaded multilingual models when enabling multiple languages. It also has an option to disable the ability to use language-specific models, as shown in the attached picture below.

This allowed the app to use the same multilingual models for all languages.

I believe this can open the gates for effectively implementing #683 and all of its duplicate and related issues like #140, #226, #684, #425, #74, #478, #158, etc.

Just wanted to check in on the progress so far (if any) regarding this feature request. I also wanted to point out that since this feature request can make it easier to implement other features involving intelligent multilingual functionality, it would be great if @dean-futo changes the priority of this issue to "high" so it doesn't get discarded over time.

Will this feature get implemented? I have multilingual models that can benefit from it.

Yes. Multilingual typing is a mid-term priority for us and this will come once that's implemented.
