Rework how the result matching is performed. Some tests from
gfxbench provide more than 1 score per test and
some provide their output in a different format to others.
Update the matching to perform more flexible matching as well
as dealing with entries that do not fit on a single results screen.
* Updated regex to reflect correct test name.
* Enabling/disabling tests on setup was missing tesselation on some devices
so changed order of toggle.
* Sometimes whilst collecting scores the workload grabs the wrong score.
Updated to check the name of the test before grabbing the score.
* Tested on mate20, xperia, s9-exynos, s10-exynos, pixel-4
Some devices print non standard characters to logcat. If an error
occurs when parsing the output, replace the offending character instead
of raising an error.
On some devices the score string obtained can contain extra characters.
Only use the numerical values from the score when converting, otherwise
if not found set the result to 'NaN'.
By clearing the application data each time the workload is run this
forces the required assets to be re-installed each time. As the
workload is not affected by persistent state do not perform the
clearing.
Creating a new workload to execute the following tests on GFXBench.
* Car Chase
* Car Chase Offscreen
* Manhattan 3.1
* 1080p Manhattan 3.1 Offscreen
* 1440p Manhattan 3.1 Offscreen
* Tessellation
* Tessellation Offscreen
