[cppia] extern static property getter

[kevinresol]

cpp host code:

class Host {
	public static function main() {
		trace(Test.foo); // bring the class into compilation
		cpp.cppia.Host.runFile('bin/script.cppia');
	}
}

cppia script code:

class Script {
	static function main() {
		trace("Hello from script!");
		trace(Test.foo);
	}
}

and Test.hx file for both

#if cppia
extern class Test {
	static var foo(get, never):Int;
}
#else
class Test {
	public static var foo(get, never):Int;
	static function get_foo():Int return 42;
}
#end

will result in error:

Unknown function : Test_obj::get_foo(0)
Error : Unknown global:Test_obj::get_foo

Turns out I need to also declare the get_foo function in the extern.
But that's weird because instance properties (i.e. non-static) work without the getter declaration in the extern.
