Fix macOS move text shortcuts on wasm

- Replaced the previous macOS-specific check with a more flexible platform detection using `cfg_if` to identify Apple devices across different environments (macOS, iOS, iPadOS, and WebAssembly).
- Introduced a boolean variable `is_apple` to streamline the logic for determining modifier keys based on the platform.
- Ensured that the shortcut behavior remains consistent for Apple devices by adjusting the modifier key checks accordingly.
