Unify rooting via webusb instead of webserial

[stylesuxx]

As suggested by @D3VL-Jack the webserial polyfill for webusb could be used instead of webserial. This would allow us to have the user only interact once with the device selection dialog for both rooting and wtfOS related things.

This could also allow us to determine rooted state and evolve the UI to hold the users hand more.

Ah yeah, right - now I can remember why I did not use it in the first place - this has actually been an issue with my other configurator too: there are no remove and connect listeners, I submitted a patch which was not merged and the maintainer did not yet implement their intended clean solution.

We could technically use my temporary fix branch...

The web-serial-polyfill does not want to cooperate if web serial itself is available, I simply can't claim the device, even with them demo.html provided in the repo I end up getting an error when attempting to open the device:

serial.ts:311 Uncaught (in promise) Error: Error setting up device: NetworkError: Failed to execute 'claimInterface' on 'USBDevice': Unable to claim interface.
    at SerialPort.open (serial.ts:311:13)
    at async demo.html:64:7

Presumably you made sure nothing else is claiming the iface? Anything in device-logs? Or maybe some udev bullshit?

[stylesuxx]

Yes, I did check that nothing else is claiming the interface. device-logs seem fine, nothing out of the ordinary. I am not the only one having this "issue" though.

You could cross check by running the demo.html from the webserial polyfill repo. As far as I understand the problem is that the system has a driver for the USB Serial device and thus can not be wrapped with the polyfill...

[j005u]

Same, with "Interface 4 uses driver "usbser" instead of WinUSB." in device-log.

So I guess without having the user involve Zadiq, we're boned? Don't want to do that, as then Assistant would break.

[stylesuxx]

Yup, I see it the same way. I don't want to involve external (non cross platform) tools at all.

Failed to execute 'claimInterface' on 'USBDevice': Unable to claim interface
Is the exact same error I was seeing when working with the BULK interface, @j005u is absolutely right about winusb driver
