drm-tests: refactor nv12_test to use bsdrm and planes
This test used to use the atrocious "sp" library. This CL removes that
dependency by using bsdrm, gbm, and its own drawing code. In particular,
the usage of gbm and bsdrm enhance this test because gbm uses hardware
specific knowledge to generate properly aligned buffer objects, and
bsdrm will automatically make proper framebuffers out of them.
In addition, this test transitions to using an overlay plane to output a
NV12 surface. The hardware that was used to test this change only
supports the NV12 on planes.
