This reverts commit 5627d65146.
Reason for revert: Google3
Original change's description:
> Add method to sk_gpu_test::TestContext to automatically restore the previous context.
>
> The motivation for this is to allow a GM to create a GL context, do some some work in it, and then return to the context that was set when it was invoked.
