Add a sanitization checkbox for the traced values that come from the JS execution tracing

Currently #5363 adds the UI to visualize the traced values coming from the JS execution tracing. We currently always remove these values during sharing to not leak any user information. But ideally we should have a checkbox for it so users might choose to upload their traced values.

And we should make it unchecked by default all the time. Currently we are checking all of them if they are in the firefox nightly channel. But this is sensitive enough that we should always default to removing them and it has to be user's conscious decision to share them.
