[js/webgpu] Introduce trace support (#18928)

This is to leverage console.timeStamp to add a single marker to
browsers' (only Chromium and Firefox support it) performance tool. With
this support, we can dump both CPU and GPU timestamps, and use
post-processing tool to clearly understand the calibrated timeline. A
demo tool can be found at https://github.com/webatintel/ort-test, and
more detailed info can be found at
