[PATCH 1/5] 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.
