SF: Add and use MockGraphicBufferProducer/Consumer
This has the benefit of allowing the tests to set expectations on the
producer/consumer queue calls.
Additionally this speeds up test execution (though possibly only for the
first test which creates a buffer queue) by a factor of 4x.
[Test execution time reduced from 25ms to 6.1ms]
Test: libsurfaceflinger_unittest passes on Pixel XL
Bug: None
