Deflake RTCPeerConnection-track-stats.https.html.

This CL does the following:

1. Add a test that verifies we have a succeeded candidate pair in
   getStats() as soon as iceConnectionState is "connected". This is
   currently flaky (https://crbug.com/926170) and marked as such.
2. Add workaround to RTCPeerConnection-track-stats.https.html so that
   it does not flake due to 1), and mark it not flaky.
3. Move shared helper functions to RTCPeerConnection-helper.js.
4. Add test coverage for making sure we can become connected in the
   recvonly use case. This requires changing the prefix to
   ".https.html" of "RTCPeerConnection-iceConnectionState".

Ran 62 tests and 778 subtests
OK     : 50
PASS   : 436
FAIL   : 320
TIMEOUT: 13
NOTRUN : 15

Existing tests that now have a worse result (e.g. they used to PASS and now FAIL):
/webrtc/RTCPeerConnection-track-stats.https.html: TIMEOUT
    RTCPeerConnection.getStats(receivingTrack) is the same as RTCRtpReceiver.getStats(): NOTRUN
    RTCPeerConnection.getStats(sendingTrack) is the same as RTCRtpSender.getStats(): NOTRUN
    RTCPeerConnection.getStats(track) throws InvalidAccessError when there are multiple senders for the track: NOTRUN
    RTCPeerConnection.getStats(track) throws InvalidAccessError when there are zero senders or receivers for the track: NOTRUN
    RTCRtpReceiver.getStats() contains only inbound-rtp and related stats: NOTRUN
    RTCRtpSender.getStats() contains only outbound-rtp and related stats: TIMEOUT

New tests that have failures or other problems:
/webrtc/RTCIceConnectionState-candidate-pair.https.html: TIMEOUT
    On ICE connected, getStats() contains a connected candidate-pair: TIMEOUT
/webrtc/RTCPeerConnection-iceConnectionState.https.html
    connection with one data channel should eventually have connected connection state: FAIL

Tests that are disabled for instability:
