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()
}

lauch profile:

    "version": "0.2.0",
    "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: How to enable new pprof labels features? #3173

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