Revert "Check for ANGLE's implementation of texture_rectangle"

This reverts commit 00f8866a321332f07520e3c12963aa1332bb7e82.

Reason for revert: Seems to be breaking angle test bots. Eg:
https://chromium-swarm.appspot.com/task?id=3dcb7f58728de610&refresh=10

Original change's description:
> Check for ANGLE's implementation of texture_rectangle
> 
> ANGLE has implemented extension to support for texture_rectangle. Check
> for its existence as well as GL_ARB_texture_rectangle extension.
> 
> Intended to follow up on Chrome side to avoid copy into texture 2d for
> PaintCanvasVideoRenderer.
> 
> Bug: skia:7903
