Attachment: Bug 1592729 - Add tests to ensure that the Picture-in-Picture toggle and context menus do not display for MediaStream videos. r?Gijs

This also updates the canToggle=false code paths in the Picture-in-Picture
mochitest head.js file, which were obviously never really exercised until
now.

Beta/Release Uplift Approval Request

• User impact if declined: Users on Windows who want to use the upcoming Picture-in-Picture feature can potentially enter a state where they end up seeing a really glitchy video feed from MediaStream video sources (example: camera feeds, screen feeds).
• Is this code covered by automated tests?: Yes
• Has the fix been verified in Nightly?: Yes
• Needs manual test from QE?: No
• If yes, steps to reproduce:
• List of other uplifts needed: None
• Risk to taking this patch: Low
• Why is the change risky/not risky? (and alternatives if risky): This adds an additional condition to the methods that determine whether or not to display the PiP toggle and context menu item. It also adds an additional check within the code that triggers PiP to ensure that these types of videos can't be opened in an always-on-top player.
• String changes made/needed: None.
