Implement depth clip control which controls if fragments
with depth values outside of [0, 1] are clipped or not.

* Source/WebCore/PAL/pal/graphics/WebGPU/Impl/WebGPUDeviceImpl.cpp:
(PAL::WebGPU::convertToBacking):

* Source/WebGPU/WebGPU/HardwareCapabilities.mm:
(WebGPU::baseFeatures):
All devices support depth clamping.
