Add VDA decode time test and refactor.

This measures the median of the decode time of all the frames.
VDA::Decode is called 30 times per second to simulate WebRTC.

VideoDecodeAcceleratorTest class is renamed to
VideoDecodeAcceleratorParamTest, which shows it is a
value-parameterized test. The common code is moved to a new
test fixture VideoDecodeAcceleratorTest, which is inherited
by VideoDecodeAcceleratorParamTest. The future new tests should
be based on VideoDecodeAcceleratorTest if they do not need to
test different combinations of the parameters.
