Fix flaky LayerTreeHostCopyRequestTestDeleteTexture test.

Fix flaky LayerTreeHostCopyRequestTestDeleteTexture test.

Because CopyOutputRequests make an extra RenderPass, which is backed
by a texture, we do a follow-up draw to remove that texture. This
raced with the texture counting that the test was doing. So wait
for the draw before proceeding.

The cc/test/ changes just make a single call to TestGLES2Interface result in a
single call to TestWGC3D which makes debugging easier!

lgtm thanks for tracking this down.
