Add the support for reporting Speedometer 2.0 results to perf dashboard

https://bugs.webkit.org/show_bug.cgi?id=182089
<rdar://problem/36172346>

Rubber-stamped by Chris Dumez.

Apparently, this has always worked since the very first version of the perf dashboard added in r163688.
The relevant code is at the line 313 of report-processor.php now.

Added regression tests for this feature since we didn't have any tests four years ago.
