Add message to the profiler startup error consistent with one in proxy.js

[szegedi]

What does this PR do?

Add message to the profiler startup error, consistent with one in proxy.js. As such, this is a continuation of #5242.

Motivation

Exceptions thrown in the async part of profiler initialization would not get the message that points to the troubleshooting link. Now they do. Before the change a telemetry log message from here would look like this:

{
  level: 'ERROR',
  count: 1,
  message: 'Generic Error',
  stack_trace: 'Error: BOOM! Async profiler startup error\n' +
    '    at Profiler._start (dd-trace/src/profiling/profiler.js:65:11)\n' +
    '    at Profiler.start (dd-trace/src/profiling/profiler.js:54:17)\n' +
    '    at Object.start (dd-trace/src/profiler.js:30:21)\n' +
    '    at Tracer._startProfiler (dd-trace/src/proxy.js:219:36)\n' +
    '    at Tracer.init (dd-trace/src/proxy.js:152:40)'
}

After the change:

{
  level: 'ERROR',
  count: 1,
  message: 'Error starting profiler. For troubleshooting tips, see <https://dtdg.co/nodejs-profiler-troubleshooting>',
  stack_trace: 'Error: BOOM! Async profiler startup error\n' +
    '    at Profiler._start (dd-trace/src/profiling/profiler.js:66:11)\n' +
    '    at Profiler.start (dd-trace/src/profiling/profiler.js:54:17)\n' +
    '    at Object.start (dd-trace/src/profiler.js:30:21)\n' +
    '    at Tracer._startProfiler (dd-trace/src/proxy.js:219:36)\n' +
    '    at Tracer.init (dd-trace/src/proxy.js:152:40)'
}

That is, it shows something more useful than "Generic Error".

nit: Feels a bit weird to have a different prototype for error()
