[WebGPU] Add support for GPU Frame capture
https://bugs.webkit.org/show_bug.cgi?id=249011

Reviewed by Dean Jackson.
Add support for capturing the nth-frame during rendering
via notifyutil -p com.apple.WebKit.WebGPU.CaptureFrame as
well as the initial frame which includes all of the resource
creation commands in the gputrace via ...ToggleCaptureFirstFrame
Requires launching the process with __XPC_METAL_CAPTURE_ENABLED=1
