Refactor Windows work area handling for improved frame overhang management

- Introduced separate constants for native and CEF window frame overhangs to accommodate different rendering contexts.
- Updated `getMaximizedWorkAreaFrame` to accept a window parameter, allowing dynamic selection of the appropriate overhang based on the window type.
- Enhanced `isWindowWorkAreaMaximized` and `clampWindowToWorkArea` functions to utilize the updated frame overhang logic, improving accuracy in window positioning.
