Reviewed by Said Abou-Hallawa.

Some devices have refresh rates that are not 60fps (like ProMotion @ 120Hz),
and run requestAnimationFrame at that speed. Update MotionMark so that:

- it doesn't hard-code 60fps everywhere
- it attempts to detect the system frame rate
- the results make it clear what frame rate the tests were using

* PerformanceTests/MotionMark/developer.html:
    Add the system frame rate and some related text.
* PerformanceTests/MotionMark/resources/debug-runner/graph.js:
    Get the graphing component to read the frame rate provided
    by the results.
(updateGraphData):
(createComplexityGraph):
(onGraphTypeChanged):
* PerformanceTests/MotionMark/resources/debug-runner/motionmark.css:
(#frame-rate-detection span): Make this red when we're in progress.
* PerformanceTests/MotionMark/resources/debug-runner/motionmark.js:
    Detect the system frame rate.
* PerformanceTests/MotionMark/resources/runner/motionmark.css:
(section .body p): This text got longer, so give it a max-width.
* PerformanceTests/MotionMark/resources/runner/motionmark.js:
    Add support for variable frame rates where necessary.
* PerformanceTests/MotionMark/resources/statistics.js:
    Ditto.
* PerformanceTests/MotionMark/resources/strings.js:
    Add a new string.
* PerformanceTests/MotionMark/tests/resources/main.js:
    Support for variable rates.
