**Is your feature request related to a problem? Please describe.**
The clipboard module depends on the remote module on Linux.

**Describe the solution you'd like**
It should be implemented using dedicated IPCs that are properly validated to avoid security issues.

**Describe alternatives you've considered**
The app can call the clipboard APIs in the main process in response to app-level IPCs from the renderer.

**Additional context**
