* Adding macOS FileSystemWatcher, this should allow files to be monitored and update like the other OSs
* Reworked how macOS launches processes to use NSTask which just deals with escaped and unescaped paths better
* Made a change to the ScriptsBuilder::RunBuildTool, this was adding the escaped values to the path, in reality it should be up to the underlying OS to make sure things are properly escaped, so removed those as they just end up causing issues. Also instead of appending the args to the fileName we just properly use the Arguments variable on the CreateProcessSettings
* No longer use open in order to show files in the finder, we use the proper method selectFile
* made a slight cleanup change to the MacPlatform Tick function
* Added ToNSString functions just to make that easier
* Added a ParseArguments function that will take a string and turn it into an array for NSTask
`nautilus` is GNOME file manager. Other distros might use another FM.
As a common ground we can use `xdg-open` which is a part of `freedesktop.org` and should be available almost everywhere.
Currently when you try and build macOS editor it assumes you also want to build iOS because of the way this check works which assumes if you have Xcode Installed you are ready to go. This really should not be the case, so instead lets check to see if you have the iophonesdk installed for your current Xcode if not then skip it.
This code attempts to resolve an issue where if you had a class in Assembly A and it was generic and you had a class that inherited from it in Assembly B it would not properly resolve these classes, also added an error check for if I was not able to find the TypeIndex then log it and return thus also preventing a crash when it goes to resolve the NativeType
* This resolves some issues where if you are building the actual C# dlls you also need them to be x64 based if you are targeting an x64 based target. This is a little complicated here because we set all this up ahead of time assuming that all the targets are compatible but in this case they are not so, just following what other places in the code are doing around this specifically dotnet AOT.
