Re: [webauthn] Add "willMakeCredentialWorkWithTheseConstraints()" method to the API

We discussed that. There are a couple of issues:
1. From a Relying Party UX perspective, sites would typically want to offer friendly guidance along the lines of "We're so glad you want to use Windows Hello! This is what to do next and here is what you should expect to see next time." This might be a popover, navigation, flyout pane, etc.
2. From the UA side, there is no way to tell the difference between "I am calling makeCredential because I know the user has an NFC or USB token in their pocket, pop up a prompt and ask them to tap it or plug it in" and "I'm just probing to see if I should even offer the user a new and more convenient option, so be as quiet as possible and don't annoy them if it's not there".
