Revert 98706 - Initial checkin of the compositor_model_bench tool

This tool simulates the GPU demands of Chromium's GPU-accelerated compositor. In
the current version, we simulate the performance of the existing forward
rendering model; coming changes will prototype a new model.

BUG=None
TEST=self
