Move .bss and .data tests to inline asm
...
If .bss is not properly cleared or .data is incorrectly cleared, there
is no way to tell what will happen if we try to run Rust code.

Replace scrolling with wraparound in graphical debug
...
Inspired by how Haiku does printing for its kernel debugger, this commit
gets rid of the scrolling when the bootlog reaches the end of the screen
and instead wraps around to the start of the screen. Between the last
written line and the first visible written line there is always a blank
line to provide visual separation.
Getting rid of the scrolling significantly simplifies the implementation
of graphical debug and removes the need for double buffering for
performance as we no longer need to read back the framebuffer when
scrolling which is very expensive on write-combining memory like the
framebuffer.

Move most HPET logs to the trace log level
...
This significantly reduces the amount of boot logs produced by the
kernel by default on x86. With this the full kernel boot logs now fit on
a single screen on my system.

Allocate IDT for APs on the BSP and statically allocate BSP IDT
...
This allows them to be immediately installed by kstart/kstart_ap without
having to wait for the page tables to be set up correctly. This removes
the initial IDT.

Replace the log crate with a custom logging system
...
This avoids the need to explicitly set a logger early during boot, which
reduces the amount of moving parts that could go wrong slightly. And it
cuts the kernel image size by 13kb.

Use HashMap rather than BTreeMap for scheme handles
...
According to the comments this previously wasn't done due to hashbrown
not having a const constructor. While it is true that HashMap::new() is
not const, HashMap::with_hasher() is const. HashMap::new() becoming
const is likely blocked on const traits.
This shrinks the kernel image by about 35kb.
