Crash reports are not symbolicated/processed on Simulators

[premun]

It seems we skip some steps here and the crash reports don't get symbolicated.

Crashing app is here:
https://dev.azure.com/xamarin/public/_build/results?buildId=58903&view=logs&j=84a022bb-4bdc-5585-8146-137444174249&t=d794747c-65a6-5105-c6e6-e1e37436ed3e

Or also here:

1. git clone https://github.com/dotnet/maui
2. dotnet build ./Microsoft.Maui.BuildTasks.slnf
   3 ./build.ps1 -Script eng/devices/ios.cake --project="/Users/ruimarinho/dotnet/maui/src/Controls/tests/DeviceTests/Controls.DeviceTests.csproj" --device=ios-simulator-64--results=TestResultsDirectory --binlog=device_ios.binlog

Historical reasons why we're just processing crash reports from a device:

1. There's no need to call mlaunch to get the crash report, it's already available on the file system. In other words this code is only applicable for crash reports from a device:

   xharness/src/Microsoft.DotNet.XHarness.iOS.Shared/CrashSnapshotReporter.cs

   Lines 153 to 162 in 2863beb

   	var args = new MlaunchArguments(
   	new DownloadCrashReportArgument(crashFile),
   	new DownloadCrashReportToArgument(crashReportFile.FullPath));
   	if (!string.IsNullOrEmpty(_deviceName))
   	{
   	args.Add(new DeviceNameArgument(_deviceName));
   	}
   	var result = await _processManager.ExecuteCommandAsync(args, _log, TimeSpan.FromMinutes(1));

2. We JIT in the simulator, which means that managed frames won't be symbolicated anyway (this is not entirely true on ARM64 anymore).

where is the crash log i can access if i run this local on my machine and simulator @rolfbjarne ? cc: @PureWeen @mattleibow

Crash reports are stored in the ~/Library/Logs/DiagnosticReports/ directory (for both simulator and macOS apps)
