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.

Implement `IdSet::iter_in`
...
This patch enables more expressive ways to slice and iterate over
the `Id`s in an `IdSet` with `IdSet::iter_in`, which takes an arbitrary
`IdSetSlicer`.
`IdSet::iter_in` efficiently slices out unintended inner parts and
then, within the remaining parts, skips inactive bits by using
`BitSlice::iter_ones` from the `bitvec` crate.
It also delivers several implementations of `IdSetSlicer` so OSTD
consumers can represent `Id` ranges ergonomically.
In the Asterinas kernel, `CpuSet::iter_in` enables a cleaner way to
define an interator that cycles over the CPUs.
