[Feature] Providing device support information via CLI

[NicolasDorier]

The information on https://github.com/bitcoin-core/HWI#device-support should be hard coded and able to be consumed via the HWI CLI so we can properly activate/deactivate feature in the GUI based on the detected device.

Because right now, I am scrapping github README page to have that in my middleware.

What kind of things are you looking for? Like what kind of txs can be signed? Some things can be "retrieved" by just running the command and checking the error, e.g. signmessage, getxpub.

Maybe we could add a deviceinfo command that returns device info including what things it supports.

Yes this is what I want.

I know, but this is a poor UX. This mean that the end user will try it, and see his action fail. Instead I wish to preemptively disable the action in the UI saying "Your hardware wallet does not support this action".
