Add WPTs test coverage for H265 loopback video calling.

- Sheriff? See message below.

Prior WPTs only verified that H265 could be negotiated in WebRTC,
trusting lower layer unit tests to confirm encoding and decoding is
working. In this CL we test the whole stack, confirming that both
encoding and decoding is happening for this codec using getStats().

Unfortunately, the CQ bots does not have H265 HW support so we have to
expect "PRECONDITION_FAILED" for now.

Message to Sheriffs:
  If this CL causes waterfalls to break because those bots have
  sufficient HW to run the tests (and this no longer
  "PRECONDITION_FAILED"), please consider adding the corresponding
  platform specific -expected.txt files or updating TestExpectations
  with [Pass Failure] rather than reverting this CL if possible.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure.

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
