[TASK] Enable USB for Extensions in Chrome

re #4060 (was #717)

Important

#5050 has implemented ledger-support and thus closed #4060 via #4593. Superseded legacy-issue #717 was closed, too.

Despite the above, this issue here (USB for Extensions) should stay open and WebUSB implementations should be tracked (and even pushed, e.g. via super-bounties on more general bounty-systems, like e.g. https://www.bountysource.com.

via WebUSB

From #4060 (comment))

It looks like the Chromium devs would be more open to making WebUSB available to extensions than U2F

From https://bugs.chromium.org/p/chromium/issues/detail?id=770896

We're very interested to see this happen as it would enable us to use WebUSB for the Hangouts Meet speakermic to use together with a Hotrod / CfM running in kiosk mode.

via U2F

Unverified/unconfirmed statement from Chrome project:

This is working as intended. There is currently no clean way of determining an appropriate origin of an extension for the purposes of populating clientData in the U2F protocol. Thus U2F support is limited to web pages.

Requirements

A patch for the Chrome Browser is created, which fulfills the requirements of the Chrome Team.

The patch must be accepted and applied to the public Chrome Browser.
