Added Initial Keyboard Driver Implementation

[ViktorPopp]

This PR introduces the initial implementation of the keyboard driver for InfinityOS. The driver enables basic keyboard input functionality, including:

• Capturing and processing key presses.
• Translating scancodes into ASCII characters.

Known Issues:

• Backspace functionality is not yet implemented. This will be addressed in a future update.

Testing:

• Tested with a standard PS/2 keyboard.
• Verified that key presses are correctly translated into characters.

Next Steps:

• Implement backspace handling.
• Add support for extended keys (e.g., arrow keys, function keys).
• Refine error handling and edge-case coverage.
