Capture/Replay: Initial setup for angle_capture_tests

Implements the first part (FrameCapture) of the proposal
go/frame-capture-and-interpreter-testing

Adds a basic test (CapturedTest) with a few frames. This test gets
captured by capture_tests.py into a temporary directory and the
resulting files are diff'ed with the files under expected/

A diff fails the test. When capture changes, the workflow would be to
run the command indicated by the error message in the test which will
overwrite the files with new ones so that they can be added to the CL.

Example test failure on capture change:
https://chromium-swarm.appspot.com/task?id=62b5f4034527c610
when testing https://crrev.com/c/4598046/3

Tests in CI: https://screenshot.googleplex.com/77o8vZVuj8AbFRj

Also adds a "angle_capture_tests_trace" lib with the trace just to test
that this capture also builds, the lib is not currently loaded by
anything.
