Update GetApplicationScreenSize implementation for Python, Robot, and Java

### Summary
In issue #1689, the `GetApplicationScreenSize` method in .NET was updated to use the `getApplicationScreenSize` command directly, instead of sending the `CallStaticMethod` command. This update fixed compatibility for Unreal Engine apps.

However, this change was only applied to the .NET implementation. The Python, Robot, and Java bindings still use the old approach, which causes `GetApplicationScreenSize` to not work properly with Unreal Engine apps for those languages.
