Misc improvements to RtpTransceiver unit tests and test utils.

In order to reduce the size and scope of a follow-up CL, this CL makes
some cleaning up and improvements to existing tests and adds some minor
test utility methods that will be used in the follow-up.

No change in behavior, this CL...
- Makes use of NiceMock in RtpTransceiver tests to avoid wall of text
  spam for various "uninteresting" method calls in all tests in this
  file.
- Refactors creating senders, receivers and transceivers to allow the
  follow-up CL to create such objects for kind "video" as well.
- Exposes cricket::FakeVideoEngine* to RtpTranscieverTest and allows
  adding unidirectional video codecs in the fake engine, to be used by
  the follow-up CL's tests.
- Allows creating fake video engine codecs from SdpVideoFormat in the
  fake decoder factory (already possible in the fake encoder factory).

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development
