tests/exynos: add fimg2d performance analysis
Currently only fast solid color clear performance is measured. A large buffer is allocated and solid color clear operations are executed on it with randomly chosen properties (position and size of the region, clear color). Execution time is measured and output together with the amount of pixels processed. The 'simple' variant only executes one G2D command buffer at a time, while the 'multi' variant executes multiple ones. This can be used to measure setup/exec overhead. The test also serves a stability check. If clocks/voltages are too high or low respectively, the test quickly reveals this.
