Continues on from #19202.
Following the addition of pprof labels we can now more easily understand the relationship between a goroutine and the requests that spawn them.
This PR takes advantage of the labels and adds a few others, then provides a mechanism for the monitoring page to query the pprof goroutine profile.
The binary profile that results from this profile is immediately piped in to the google library for parsing this and then stack traces are formed for the goroutines.
If the goroutine is within a context or has been created from a goroutine within a process context it will acquire the process description labels for that process.
The goroutines are mapped with there associate pids and any that do not have an associated pid are placed in a group at the bottom as unbound.
In this way we should be able to more easily examine goroutines that have been stuck.
A manager command `gitea manager processes` is also provided that can export the processes (with or without stacktraces) to the command line.

Make router logger more friendly, show the related function name/file/line.
[BREAKING]
This PR substantially changes the logging format of the router logger. If you use this logging for monitoring e.g. fail2ban you will need to update this to match the new format.
A consequence of forcibly setting the RoutePath to the escaped url is that the
auto routing to endpoints without terminal slashes fails (Causing #18060.) This
failure raises the possibility that forcibly setting the RoutePath causes other
unexpected behaviors too.
Therefore, instead we should simply pre-escape the URL in the process registering
handler. Then the request URL will be properly escaped for all the following calls.
Fix #17938
Fix #18060
Replace #18062
Replace #17997

This PR registers requests with the process manager and manages hierarchy within the processes.
Git repos are then associated with a context, (usually the request's context) - with sub commands using this context as their base context.
