Reviewed by Dean Jackson.

Configure the pipeline state to support vertex input
buffers.

This was tested against external WebGPU samples but
I will add a local test case while the review is on-going.

* Source/WebGPU/WebGPU/RenderPassEncoder.h:
* Source/WebGPU/WebGPU/RenderPassEncoder.mm:
(WebGPU::RenderPassEncoder::setBindGroup):
Offset the bind group vertex buffer by the number of
vertex shader input buffers.

(WebGPU::RenderPassEncoder::setPipeline):
Cache the number of vertex shader input buffers.

* Source/WebGPU/WebGPU/RenderPipeline.h:
(WebGPU::RenderPipeline::create):
(WebGPU::RenderPipeline::vertexShaderInputBufferCount const):
Return the number of vertex shader input buffers.

* Source/WebGPU/WebGPU/RenderPipeline.mm:
(WebGPU::Device::validateRenderPipeline):
(WebGPU::vertexFormat):
(WebGPU::stepFunction):
(WebGPU::createVertexDescriptor):
(WebGPU::Device::createRenderPipeline):
(WebGPU::RenderPipeline::RenderPipeline):
Configure the vertex shader input buffer state.

* Websites/webkit.org/demos/webgpu/scripts/textured-cube-vs-input-buffers.js: Added.
(async helloCube.frameUpdate):
(async helloCube):
* Websites/webkit.org/demos/webgpu/textured-cube-vs-input-buffers.html: Added.
Add sample test show use of vertex shader input buffers.
