Subject: [PATCH] feat: implement keyboard device management

- Added Keyboard struct and associated methods for creating and managing keyboard devices.
- Introduced error handling for device creation and validation.
- Implemented functions to enable/disable keyboards and check their status.
- Added utility function to identify keyboard devices in the X11 environment.

Log: This enhancement improves keyboard device handling within the dxinput package.
