Update VideoTexture doc with note about using RGBA format to avoid Firefox performance issue. (#21746)

* VideoTexture should use RGBA format to avoid firefox issue.

There's an issue with Firefox desktop that causes RGBFormat on a video texture to destroy performance.  When testing with a single 4K 360 video, frame times on Firefox with RGBFormat were ~200x RGBAFormat.  (62ms vs .32ms)  I propose defaulting to RGBAFormat to avoid this.

* Revert VideoTexture.js changes.

* Update VideoTexture doc with 'format' default value and note about a Firefox bug.

* WebGPURenderPipelines: Determine pipeline based on parameters.

* Add WebGPURenderPipeline.
