Kernel: Demangle userspace ELF symbols in backtraces
...
Turns out we can use abi::__cxa_demangle() for this, and all we need to
provide is sprintf(), realloc() and free(), so this patch exposes them.
We now have fully demangled C++ backtraces :^)

Kernel: Move Kernel mapping to 0xc0000000
...
The kernel is now no longer identity mapped to the bottom 8MiB of
memory, and is now mapped at the higher address of `0xc0000000`.
The lower ~1MiB of memory (from GRUB's mmap), however is still
identity mapped to provide an easy way for the kernel to get
physical pages for things such as DMA etc. These could later be
mapped to the higher address too, as I'm not too sure how to
go about doing this elegantly without a lot of address subtractions.

Whatever this was supposed to be, it was ironically... not implemented.

TTY: Properly implement echo in VirtualConsole.
...
VirtualConsole::echo now actually echoes characters
instead of doing nothing.

AK: Rename <AK/AKString.h> to <AK/String.h>
...
This was a workaround to be able to build on case-insensitive file
systems where it might get confused about <string.h> vs <String.h>.
Let's just not support building that way, so String.h can have an
objectively nicer name. :^)

These types can be picked up by including <AK/Types.h>:
* u8, u16, u32, u64 (unsigned)

Kernel: Move i386.{cpp,h} => Arch/i386/CPU.{cpp,h}
...
There's a ton of work that would need to be done before we could spin up on
another architecture, but let's at least try to separate things out a bit.
