Add KDGETMODE and KDSETMODE ioctl support
...
Add support for virtual console TTY mode management ioctls required by
Xorg and other display servers. The implementation includes:
- KDGETMODE: Query the current virtual console mode
- KDSETMODE: Switch between text and graphics modes
Virtual consoles utilize the framebuffer with two distinct modes:
- Text mode (default): Kernel renders text characters to framebuffer
- Graphics mode: User space applications gain full framebuffer control
Xorg requires KDSETMODE during initialization to switch to graphics
mode, preventing conflicts where both the kernel and Xorg would
simultaneously attempt to write to the framebuffer. This ensures
proper display handling and eliminates rendering artifacts.

Correct /dev/tty1 major number to 4
...
The major number for /dev/tty1 must be 4, as this value is hardcoded
in Linux and Linux syscall-compatible operating systems. Xorg uses
this major number directly, and incorrect values lead to confusion
and operational failures.
This change ensures compatibility with Xorg's expectations and
maintains system consistency.
