Revert "Add SkVM op trace_done to indicate completion of debug tracing."

Browse Source 
This reverts commit 062652067b.

Reason for revert: design change removes need for this op

Original change's description:
> Add SkVM op `trace_done` to indicate completion of debug tracing.
>
> This op can be used to invoke a callback function and dump the log to
> disk when it is ready. SkRuntimeEffect doesn't have any other viable
> mechanisms for detecting that a paint has completed, AFAIK. We can
> wait for ~SkRTShader to occur, but there's no guarantee that this will
> happen quickly, and the SkPaint with the SkRTShader shader can be reused
> over and over again.
>
> Unlike other trace ops, this only needs a trace mask, not an execution
> mask (we are unconditionally done at the end of main).
>
