Log worst hanging tasks and actions (#57835)

We have a lot of long blocking tasks on both the foreground and
background, this is a start of getting some insight into those.

We will now log tasks running longer then 100ms on the foreground or
background. Hanging actions will also be logged including their name. We
simultaneously collect statistics on task and action performance and
send those to telemetry. This includes quantiles and averages for each
hanging task.

Finally this adds tree dev actions: 
- hang action
- hang foreground
- hang background

These cause a hang to check if hang reporting is working and in the
future telemetry.
