  [WebGPU] Split Cocoa-specific parts of GPUCanvasContext into GPUCanvasContextCocoa

Reviewed by Dean Jackson.

GPUCanvasContext has a whole bunch of PlatformCALayer and MachPort business going on.
Ideally, all ports would be able to use GPUCanvasContext, and only differ in the
specific pieces that are platform-dependent. So we can move the PlatformCALayer and
MachPort stuff into GPUCanvasContextCocoa.

I'm aiming for a future where all WebKit ports support WebGPU; the Cocoa ports would
do so by linking with WebGPU.framework, and the non-Cocoa ports would do so by
linking with either WGPU or Dawn. The HAVE(WEBGPU_IMPLEMENTATION) macro is supposed
to indicate whether the port has actually started linking with one of those - and
therefore the macro itself is platform independent.

This patch doesn't actually have any behavior change; it just moves code around.
