UI: Include Pprof label in Goroutine name/header in the _call stack_ section of the debugger

[gm0stache]

Is your feature request related to a problem? Please describe. Pprof labels are not (directly) visible in the call stack section of the debugger.

Describe the solution you'd like I would like the Pprof labels to be visible in the call stack section of the debugger.

Consider the following program:

package main

import (
    "context"
    "fmt"
    "runtime/pprof"
    "strconv"
    "sync"
    "time"
)

func worker(name string) {
    time.Sleep(1 * time.Second)
    fmt.Println("worker finished:", name)
}

func main() {
    wg := sync.WaitGroup{}
    for i := 0; i < 20; i++ {
        wg.Add(1)
        labels := pprof.Labels("worker", strconv.Itoa(i))
        pprof.Do(context.TODO(), labels, func(ctx context.Context) {
            go worker(strconv.Itoa(i))
        })
    }
    wg.Wait()
}

    "configurations": [
        {
            "name": "Launch file",
            "type": "go",
            "request": "launch",
            "mode": "debug",
            "program": "${file}",
            "hideSystemGoroutines": true,
            "showPprofLabels": [
                "*"
            ]
        }
    ]
}

When setting a breakpoint for last line im the main function, and debugging the program, I would like to see the goroutines listed in the call stack section with the configured pprof labels clearly visible. It would make debugging goroutines more straight forward.

Additional context

• the lauch profile prop showPprofLabels is not officially supported (maybe do so?), but I used it based on information from this issue: #3173

Thanks for all your work and time! Happy to answer any upcoming questions!
