A testing cleanup. 

This pull request replaces `os.MkdirTemp` with `t.TempDir`. We can use the `T.TempDir` function from the `testing` package to create temporary directory. The directory created by `T.TempDir` is automatically removed when the test and all its subtests complete. 

This saves us at least 2 lines (error check, and cleanup) on every instance, or in some cases adds cleanup that we forgot.

Reference: https://pkg.go.dev/testing#T.TempDir

```go
func TestFoo(t *testing.T) {
	// before
	tmpDir, err := os.MkdirTemp("", "")
	require.NoError(t, err)
	defer os.RemoveAll(tmpDir)

	// now
	tmpDir := t.TempDir()
}
```

* Empty log queue on flush and close

It is possible for log events to remain in the buffer off the multichannelledlog
and thus not be logged despite close or flush.

This PR simply adds a function to empty the queue before closing or flushing.
(Except when the logger is paused.)

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.

* Add auto logging of goroutine pid label

This PR uses unsafe to export the hidden runtime_getProfLabel function from the
runtime package and then casts the result to a map[string]string.

We can then interrogate this map to get the pid label from the goroutine allowing
us to log it with any logging request.

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.

Remove repeated type declarations in function definitions.

Strangely a weird bug was present in the log escaping code whereby any escaped
character would gain 03d - this was due to a mistake in the format string where
it should have read %03o but read instead %o03d. This has led to spurious 03d
trailing characters on these escaped characters!
