Enable or disable per-frame-graph-task GPU timing.
The profiling implementation is loaded with a dynamic import on first enable. Engines that never call this
function do not fetch the profiler chunk or carry task-timing code in the always-fetched frame graph.
The returned snapshot is unsupported if the device lacks WebGPU timestamp-query, pending immediately
after enable, and available once a later frame's async timestamp readback completes.
