Reviewed by Dean Jackson.

Add depth buffer support along with a test case which shows
several intersecting rotating textured cubes.

* Source/WebGPU/WebGPU/CommandEncoder.mm:
(WebGPU::CommandEncoder::validateRenderPassDescriptor const):
(WebGPU::CommandEncoder::beginRenderPass):
Create the depth state.

* Source/WebGPU/WebGPU/RenderPassEncoder.mm:
(WebGPU::RenderPassEncoder::setPipeline):
Set the depth stencil state if it exists.

* Source/WebGPU/WebGPU/RenderPipeline.h:
(WebGPU::RenderPipeline::create):
(WebGPU::RenderPipeline::depthStencilState const):

* Source/WebGPU/WebGPU/RenderPipeline.mm:
(WebGPU::topologyType):
Set input topology type.

(WebGPU::Device::validateRenderPipeline):
Depth stencil is supported.

(WebGPU::convertToMTLCompare):
Convert compare function to metal compare function.

(WebGPU::Device::createRenderPipeline):
(WebGPU::RenderPipeline::RenderPipeline):

* Websites/webkit.org/demos/webgpu/instanced-textured-cube.html: Added.
* Websites/webkit.org/demos/webgpu/scripts/instanced-textured-cube.js: Added.
(async helloCube.frameUpdate):
(async helloCube):
Add a test case showing 9 cubes rotating with different offsets and intersecting
other cubes to illustrate a working depth buffer.
