removing google sign in modal from chrome://devices

Description

We should remove the Google Sign In modal window under chrome://devices which also includes Google branding. Because this is pretty buried, I don’t think we need to fix it for 0.55.x but should remove this before releasing 1.0..

Steps to Reproduce

1. launch b-c and load chrome://devices
2. click on sign in and you’ll get a Google sign in modal that includes Google branding

Actual result:

Expected result:

Clicking on Sign in under chrome://devices shouldn’t launch the Google modal which also includes Google branding.

Reproduces how often:

On second thought, probably a good idea to remove this sooner than later due to the Google automatically logging folks into their browser without asking issue that’s pretty hot right now.
