[web-platform-tests] Pull Request: Use getUserMedia for addTrack tests that do not involve transceivers

wpt-pr-bot has just labeled a pull request from soareschen for https://github.com/w3c/web-platform-tests as "wg-webrtc":

== Use getUserMedia for addTrack tests that do not involve transceivers ==
This is motivated by  #6453.

This modifies some tests for `addTrack` that doesn't involve transceivers and use `getUserMedia` to generate tracks instead of `addTransceiver`. 

I also removed the `assert_own_property` assertions because they are incorrectly asserting methods such as `addTrack` as missing when they are not, because `assert_own_property` doesn't look into the prototype chain.

See https://github.com/w3c/web-platform-tests/pull/6516
