Kernel: Do not do integer to pointer conversion in constexpr functions
...
Creating pointers from arbitrary values is not a valid thing to do in
constexpr functions. Furthermore, this functions is always called with
runtime values anyways, so there's no use in having it be constexpr.
Instead, make it ALWAYS_INLINE.

Kernel: Do not return a null ref in Processor::current on aarch64
...
Clang rejects binding a reference to a null pointer at compile-time.
Let's just crash explicitly, instead of waiting for a null dereference
to mess things up.

Kernel: Move incorrect early return in sys$mprotect

Since we're iterating over multiple regions that interesect with the
requested range, just one of them having the requested access flags
is not enough to finish the syscall early.

Kernel: Replace usages of SIGSTKFLT with SIGSEGV
...
SIGSTKFLT is a signal that signifies a stack fault in a x87 coprocessor,
this signal is not POSIX and also unused by Linux and the BSDs, so let's
use SIGSEGV so programs that setup signal handlers for the common
signals could still handle them in serenity.

The advices are almost always exclusive of one another, and while POSIX
does not define madvise, most other unix-like and *BSD systems also only
accept a singular value per call.

Kernel: Add an error propagating KString::format(..) API :^)
...
In the continuous effort of better handling OOM in the kernel,
we want to move away from all AK::String usage. One of the final
pieces left to accomplish this goal is replacing all of the usages
of `String::formatted` with something that can actually propagate
failure.
The StringBuilder API was enhanced in the recent past to propagate
failure and thus a slightly modified version of what exists in
`AK::format` will work well for implementing failable format with
`KString`.
