feat: Nintendo Switch support

[bitsandfoxes]

We'll need to find a way to deal with statically built sentry-native.

Follow up on fixing the installation instructions in https://github.com/getsentry/sentry-switch/pull/26

Todos:

• Import sentry-switch
• Figure out how to load sentry-native as a static lib
• AnalyticsSessionInfo::get_userId is not valid
• The reported operating system name is Nintendo OS. See feat: parsing for Nintendo Switch os.name relay#4821
• Log Forwarder throws with: Unable to load 'msvcrt'
• Cannot start network transport because network_connect_func option is not set
• No support for IL2CPP line numbers. Fails here
  

  sentry-unity/src/Sentry.Unity/Il2CppEventProcessor.cs

  Lines 84 to 91 in c97e63f

  	var nativeLen = nativeStackTrace.Frames.Length;
  	var eventLen = sentryStacktrace.Frames.Count;
  	if (nativeLen != eventLen)
  	{
  	Options.DiagnosticLogger?.LogWarning(
  	"Native and sentry stack trace lengths don't match '({0} != {1})' - this may cause invalid stack traces.",
  	nativeLen, eventLen);
  	}

• Debug symbol upload? There is this .nss file
• Add capture_message to the native samples
• When writing the options, also create the proper folder structure to support Switch in Assets/Plugins/Sentry/Switch and drop a textfile in there detailing how to add/get support
