WebGPURenderer: Improve and fix texture bindings manager

[sunag]

Fixes #31480
Related issue: #28392 (comment), #29183,

Description

The PR simplify the binding generation by removing needsBindingsUpdate() and keep the texture version for update texture data only.
It also fixes the current bug and hopefully addresses a long-standing issue related to texture binding.

Thanks! Is it possible to add something like a setSize function to StorageTexture, as well, similar to RenderTarget? Otherwise I can add it tomorrow after this PR is merged. Something like so:

	setSize( width, height ) {

		if ( this.image.width !== width || this.image.height !== height ) {

			this.image.width = width;
			this.image.height = height;
			this.image.depth = depth;

			this.dispose();

		}

	}
