Make JNISafety safe for macro context

[tobil4sk]

There is a regression in 8.3.0 (specifically 8f0b8f3) which has broken builds for android apps that use macros, e.g.:

class Main extends lime.app.Application {
	macro static function test() {
		return macro "hello";
	}
	
	public function new () {
		super ();
		test();
	}
}

$ lime build android
/.../lime/src/lime/_internal/backend/native/NativeApplication.hx:1052: character 9 : You cannot use @:build inside a macro : make sure that your type is not used in macro
/.../lime/src/lime/_internal/backend/native/NativeApplication.hx:95: characters 31-87 : lime._internal.backend.native._NativeApplication.OrientationChangeListener does not have a constructor
/.../lime/src/lime/app/Application.hx:61: characters 30-55 : Unknown<0> cannot be constructed

This is because src/lime/_internal/backend/native/NativeApplication.hx now has OrientationChangeListener, which extends JNISafety which is marked with @:autoBuild.

We can avoid the error by skipping the @:autoBuild meta in the macro context.
