1) Added ForegroundViewport as a new color. It is used in the main game viewport (ViewportWidgetButton), and the viewport for rendering of particles and materials. It is needed because the default foreground in a Light theme is black, but black does not work well in a viewport. A new color seemed appropriate.
2) Fixed the profiler window to use the Foreground color in multiple text elements, instead of Color.White (or no default TitleColor). This includes the Row class, Asset class, SingleChart class, Timeline Class, and more.
3) Added a second theme/Style (DefaultLight) to include with the engine. It uses RGB float values because those were easier to transfer from the saved values that I had created (and they're easier for me to edit if necessary). I tried to emulate how the Default theme is created/loaded/etc as closely as possible.
* Fixing issues where when the editor would try and launch rider on an M1/2 machine it would not properly open because it was the wrong architecture which is now resolved because open will do the right thing
* Making the ParseArgs function a little more resilient against escaped arguments
* 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.
