This is to alleviate problems due to the command buffer getting bent out of shape when the current
OpenGL context is switched out from under it (because we ran a test with a native GL context). This,
however is not a full solution. More changes will be required to ensure that after running each
command buffer or native test we bind the null context. This does allow us to take a step in that
direction without breaking anything too badly. Moreover, there is no real benefit to reusing a
GrContextFactory.
Modifies DEF_GPUTEST to take GrContextOptions rather than a factory to use. Tests were already using
their own factories anyway.
In tests that use GrContextFactory the factory instance is moved to the inner loop.
Modifies gpucts and skia_test to not use persistent GrContextFactories.
