[dart:html] Unsuppress MediaDevices.getUserMedia

Bug: https://github.com/dart-lang/sdk/issues/35253

This API was suppressed initially due to issues with conversions
between promises and futures. Now that that has been resolved, this
should be unsuppressed. Tests have been refactored to use both
navigator.getUserMedia and navigator.mediaDevices.getUserMedia.
