Create onboarding flow

[Bosch-0]

Closed the Widgets GUI issue on onboarding considerations to re-open here.

Past discussion can be found here: bitcoin-core/gui#81

Does bitcoin-core/gui#81 (comment) point to the latest figma design files? Maybe post the link here?

The mockup I did in that original post can be found here.

Though I will be creating an onboarding flow from scratch for the QML GUI as that design was done within the constraints of widgets.

We should focus any onboarding related discussions to this thread.

See #43.

Do we still need this issue? #43 was closed a month ago and while there is an onboarding flow in development in #127, the conversations around it are not happening in this thread.
