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.

* [Doc/zh]: Update PCDLoader.html

* [Doc/zh]: Update PCDLoader.html

* Get linear and angular velocity for targetRay and grip poses if available

WebXR spec has been updated allowing the User Agent to pass along linear and angular velocity values for the controller poses. Read this if it's available and pass attach to the _targetRay and _grip structures.

See https://immersive-web.github.io/webxr/#xrpose-interface for more info.

* fixed linting errors

* more linting issues :\

* third time's a charm

* fix check for existence of angular and linear velocity to fail gracefully when not present

* simplified to use copy instead of set

* Update WebXRController.js

Clean up code style.
