[mediacapture-main] Pull Request: Allow gUM prompt ahead of focus + deterministic "visible" enumeration wo/focus

jan-ivar has just submitted a new pull request for https://github.com/w3c/mediacapture-main:

== Allow gUM prompt ahead of focus + deterministic "visible" enumeration wo/focus ==
Fixes https://github.com/w3c/mediacapture-main/issues/752:
1. Relax document (iframe) focus to tlbc [system focus](https://html.spec.whatwg.org/multipage/interaction.html#tlbc-system-focus) (a step in the right direction)
2. Allow Safari prompts in foreground tabs, while maintaining focus requirement on allow, per https://github.com/w3c/mediacapture-main/issues/752#issuecomment-921352150
3. Remove focus requirement on enumerateDevices, per https://github.com/w3c/mediacapture-main/issues/752#issuecomment-1293797299
4. Fix race spotted in https://github.com/w3c/mediacapture-main/issues/905#issuecomment-1293812378 which prevented deterministic visibility-success checks:
   if (document.visibilityState == "visible") {
     await navigator.mediaDevices.enumerateDevices(); // won't block on visibility
