Add new provider for gc-collect profile

[dramos020]

Adds the profile mentioned in #3521 in order to include private gc events in the gc-collect profile. Can see this working by using the following sample application:

using System.Collections;

class ConsoleTest{
    public static void Main(){
        List<int> nums = new List<int> {};

        Console.WriteLine("Currently Running");
     
        while(true){
            List<object> objects = new List<object>();
            for (int i = 0; i < 100000; ++i)
            {
                objects.Add(new object());
            }
            objects.Clear();
        }
    }
}

and dotnet-trace to collect a trace:

dotnet-trace collect --profile gc-collect -n sampleapp

This results in the following events being generated, making note of the private gc events:

thanks @hoyosjs! I'm curious why those rundown events are there even though they are not in the list of events we collect for this profile?

Currently dotnet-trace is hardcoded to always request rundown, the true as the second parameter here is to request rundown:

diagnostics/src/Tools/dotnet-trace/CommandLine/Commands/CollectCommand.cs

Line 228 in 574923f

session = diagnosticsClient.StartEventPipeSession(providerCollection, true, (int)buffersize);

We should generally have an option to skip rundown, I opened #3597 to track it.

LGTM, thanks Daniel!
