  [WebGPU] Expand metal capture to capture a number of calls to submit

Reviewed by Dan Glastonbury.

Some websites may call GPUQueue.submit several times per frame so
to capture the entire list of submissions we need to allow the capture
to continue across multiple calls to GPUQueue.submit.

Allow specifying the state of CaptureFrame like so:
notifyutil -s com.apple.WebKit.WebGPU.CaptureFrame 10

to capture 10 submit calls.
