XCode frameworks support

- supported as "Link with Libraries".
- Frameworks added as a group to the project
- no need to specify custom linker flags anymore, xcodeproj works just like ninja

example mason.build file :
dep_main += [dependency('appleframeworks', modules : ['Foundation', 'AppKit', 'IOKIT', 'QuartzCore', 'OpenGL', 'GLUT', 'OpenAL'], required : true)]
