Get GpuCrashTest running in content_browsertests.

Get GpuCrashTest running in content_browsertests.

1) The test class name should begin with "Gpu" to be picked by gpu bot filters.

2) implify gpu crash tests by directly call the SimulateCrash function. Before we open a new tab, go to about:gpucrash.  This is really unnecessary.

3) Disable infobar stuff for Kill - otherwise the GPU process won't launch after crashing.

4) Clean up the webgl.html a little bit.

Ken: please have a look.

Once this runs fine in content_browsertests, I will remove the chrome side
tests.

LGTM

There's one new test in src/chrome/test/gpu/gpu_crash_browsertest.cc
(GPUCrashTest.ContextLossRaisesInfobar) which I'd like to preserve if at all
possible. Maybe we can add our own WebContentsObserver overriding DidBlock3DAPIs
and ensure that that method is called against it after calling SimulateGPUCrash?
This doesn't have to be done in this CL.

Sure.  When I said I would remove the chrome side tests, I wasn't planning to
remove the WebGL infobar tests.
