Refactor menu functions and streamline devtools toggle across systems

This update adds implementation to several menu item functions, replacing their previous 'not implemented' state. This includes actions for close, reload, forcing reload, toggling of fullscreen, reset zoom, and others. The update also includes modifications for the handling of developer tools toggle under different build configurations. This refactoring is aimed to standardize devtools configuration across different operating systems.
