## Description

Previously, such function is only available in the debug mode. But the
performance information is very noisy in debug mode with JIT. I feel
that such function is as important and useful as the performance overlay
and the `--trace-skia` option for the GPU thread.  So we should give it
the same ability to run in both profile and debug mode.

I've tested it using flutter_gallery in the profile mode. There's no
observable difference in the performance overlay between toggling widget
build profiling.
