allow further texture uniforms

[bkuster]

Description

The number of image data types available to Materials should be upgraded with some more data types:

• OffscreenCanvas (can just be passed to WegGL, same as HTMLCanvasElement).
• ImageBitmap (can be directly consumed by the GPU).

In my usecase, I already have an ImageBitmap created in a worker and would like to avoid having to draw it onto a canvas to then pass it to the Texture, when I could just pass it directly.

Testing plan

Added tests to MetarialSpec.js for both use cases.

Thanks @bkuster! The code change looks good to me. I think we only need to extend the docs update to a couple more places inside Texture. Then this should be good to go!
