7a206868f8 Kernel: Move architecture dependent includes to the top in Processor.h 
With the declaration order dependency resolved in the last two commits
we can now do this, which looks a lot nicer.

e34eb3e36d Kernel: Remove unused String.h includes 
This makes searching for not yet OOM safe interfaces a bit easier.

39ecb832e4 Kernel: Don't try to dispatch urgent signals for kernel crashes 
If we crashed in the kernel there's no point to sending a signal to the
active process, we're going to panic soon anyway.

8e2d0c8d5c 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.

40f64d7379 Kernel: Dispatch handle-able signals instead of crashing if possible 
This matches the behaviour of the other *nixs and allows processes to
try and recover from such signals in userland.

a9e436c4a3 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.

216e21a1fa AK: Convert AK::Format formatting helpers to returning ErrorOr<void> 
This isn't a complete conversion to ErrorOr<void>, but a good chunk.
The end goal here is to propagate buffer allocation failures to the
caller, and allow the use of TRY() with formatting functions.

65edc62c02 Kernel: Resolve clang-tidy readability-make-member-function-const

Some places the warning is suppressed, because we do not want a const
object do have non-const access to the returned sub-object.

79fa9765ca Kernel: Replace KResult and KResultOr<T> with Error and ErrorOr<T> 
We now use AK::Error and AK::ErrorOr<T> in both kernel and userspace!
This was a slightly tedious refactoring that took a long time, so it's
not unlikely that some bugs crept in.

Nevertheless, it does pass basic functionality testing, and it's just
real nice to finally see the same pattern in all contexts. :^)

sets regs.gs, but not vice versa.

17b66eaa3c Kernel: Call try_set_coredump_property with StringView arguments 
Storing assigning a string literal to a String object just to pass it to
a function expecting a StringView is wasteful. Let's just not do that.

For consistency's sake, this commit changes all of the other invocations
to use StringView literals, too.
