feat: pprof for coder agent is always on

[mtojek]

Fixes: #2081

This PR enables the pprof endpoint for the coder agent by default. It may result in port conflicts if there is another application listening on that port (127.0.0.1:6060).

Is port 6060 used frequently for development by any language? I'd hate to modify someone's workflow if they adopt Coder.

I also believe our port forward dialog will pick this up and display it in the UI, which we should disable. It might be worth considering only doing this behavior on Windows, but that's also kinda jank.

Looking at the speedguide stats, it seems to be mostly related to pprof debugging, so it should be safe.

I think that it's worth keeping the consistent behavior, otherwise, we may confuse people working on different OS platforms. I'm pretty sure that users will survive with 1 more reserved port.

I understand that we wouldn't like to expose the 6060 in the port-forward mode, am I correct? I'm wondering if it isn't a feature to allow for accessing it, even for customer debugging purposes (heap dump?)
