gpu: Perf test to check costs of texture upload at different stages.
Simple test that uploads and draws a texture on an offscreen surface.
The upload/draw code is run multiple times, timings are collected and the
average elapsed milliseconds are printed out using the perf_test framework.
The test target has not been added to the perf tests the are automatically run yet
and has to be manually run.
