This reverts commit 4e37751693.
Reason for revert: breaking some mac test bots
Original change's description:
> Make it easier to test rectangle textures by using createBackendTexture.
>
> Also allows internal creation of rectangle textures, only used by unit
> tests currently.
>
> Previously GrContext::createBackendTexture() would ignore the request
> for RECTANGLE or EXTERNAL and always make 2D. Now it makes RECTANGLE if
> supported and always fails for EXTERNAL.
