[epic] connect - mobile support - phase 1

[mroz22]

Goal: give the 3rd parties the ability to talk to Trezor devices easily.

Suite-lite as connect provider #13648

• @Nodonisko creates a PR with very basic barebones of the project so that we know where we put our code.
• trezor-suite-lite is capable of handling deep links, which are connect API calls. It hands over such a call to its internal instance of connect and returns the response via a callback URL provided in the link.
• some basic UI within trezor-suite-lite
• there should be a thin package exposing trezor-connect API with deeplinks as the underlying communication mechanism
• example of a client application for demonstration purposes.

followups

UI-less SDK #13647

we are not sure if want to do it - it would bundle all the expo modules which is probably too heavyweight for 3rd parties to implement. @Nodonisko has some ideas how it could be solved but it is still in the making

• self-contained within the monorepo structure - I should be able to import and use it. If there is any platform-specific work, it should be documented in a readme file.
• suite-lite is using this SDK
• we can run @trezor/connect e2e tests in react-native environment
• consider expo vs non-expo?
• consider connect - core - option to force all inputs on device #13646
• consider releasing it as an npm package and mentioning it in the public documentation.
