7c0540a229 Everywhere: Move global Kernel pattern code to Kernel/Library directory
This has KString, KBuffer, DoubleBuffer, KBufferBuilder, IOWindow,
UserOrKernelBuffer and ScopedCritical classes being moved to the
Kernel/Library subdirectory.

Also, move the panic and assertions handling code to that directory.

a6a439243f Kernel: Turn lock ranks into template parameters
This step would ideally not have been necessary (increases amount of
refactoring and templates necessary, which in turn increases build
times), but it gives us a couple of nice properties:
- SpinlockProtected inside Singleton (a very common combination) can now
  obtain any lock rank just via the template parameter. It was not
  previously possible to do this with SingletonInstanceCreator magic.
- SpinlockProtected's lock rank is now mandatory; this is the majority
  of cases and allows us to see where we're still missing proper ranks.
- The type already informs us what lock rank a lock has, which aids code
  readability and (possibly, if gdb cooperates) lock mismatch debugging.
- The rank of a lock can no longer be dynamic, which is not something we
  wanted in the first place (or made use of). Locks randomly changing
  their rank sounds like a disaster waiting to happen.
- In some places, we might be able to statically check that locks are
  taken in the right order (with the right lock rank checking
  implementation) as rank information is fully statically known.

This refactoring even more exposes the fact that Mutex has no lock rank
capabilites, which is not fixed here.

b18a7297c5 Kernel: Move ScopedCritical.cpp to Kernel base directory
This file does not contain any architecture specific implementations,
so we can move it to the Kernel base directory. Also update the relevant
include paths.

ae3ffdd521 AK: Make it possible to not using AK classes into the global namespace
This patch adds the `USING_AK_GLOBALLY` macro which is enabled by
default, but can be overridden by build flags.

This is a step towards integrating Jakt and AK types.

828441852f Everywhere: Replace uses of __serenity__ with AK_OS_SERENITY
Now that we have OS macros for essentially every supported OS, let's try
to use them everywhere.

18257604eb Lagom: Win32 support baby steps
This is the initial port of Lagom to win32. This will enable developers
to use Lagom as an alternative to vanilla STL/StandardC++Library - which
gives a much richer environment (think QtCore - but modern).

My main incentive - is to have a native Windows Ladybird working.

I am starting with AK, which does not yet fully compile (on mingw). When
AK is compiling (currently fails building StringBuffer.cpp) - I will
continue to LibCore and then the rest of the user space libraries
(excluding the GUI, which will be another different effort).

Most of the code is happily stollen from Andrew Kaster's fork - he
deserves the credit.

4809dc8ec2 AK: Add Singleton special-case constructor for SpinlockProtected
This will allow Singletons of that class to still be created when
SpinlockProtected can't be constructed without a lock rank argument
anymore.

f4fb637914 Kernel: Split ScopedCritical so header is platform independent
A new header file has been created in the Arch/ folder while the
implementation has been moved into a CPP living in the X86 folder.

545ce5b595 Kernel: Add per platform Processor.h headers
The platform independent Processor.h file includes the shared processor
code and includes the specific platform header file.

All references to the Arch/x86/Processor.h file have been replaced with
a reference to Arch/Processor.h.

1682f0b760 Everything: Move to SPDX license identifiers in all files.
SPDX License Identifiers are a more compact / standardized
way of representing file license information.

See: https://spdx.dev/resources/use/#identifiers

This was done with the `ambr` search and replace tool.

0d934fc991 Kernel::CPU: Move headers into common directory
Alot of code is shared between i386/i686/x86 and x86_64
and a lot probably will be used for compatability modes.
So we start by moving the headers into one Directory.
We will probalby be able to move some cpp files aswell.

5d180d1f99 Everywhere: Rename ASSERT => VERIFY
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)

Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.

We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.

cc89606ba8 Everywhere: Remove unnecessary headers 3/4
Arbitrarily split up to make git bisect easier.

These unnecessary #include's were found by combining an automated tool (which
determined likely candidates) and some brain power (which decided whether
the #include is also semantically superfluous).

1fc7d65aad AK: Add static Singleton::get function to allow destructible globals
This enable using global raw pointers rather than Singleton objects,
which solves some problems because global Singleton object could
be deleted when destructors are run.

Everywhere: Switch from (void) to [[maybe_unused]] (#4473)
Problem:
- `(void)` simply casts the expression to void. This is understood to
  indicate that it is ignored, but this is really a compiler trick to
  get the compiler to not generate a warning.

Solution:
- Use the `[[maybe_unused]]` attribute to indicate the value is unused.

Note:
- Functions taking a `(void)` argument list have also been changed to
  `()` because this is not needed and shows up in the same grep
  command.

7d8a9bdb1e AK: Cleanup missing includes and #ifdef evaluation
Problem:
- Several files have missing includes. This results in complaints from
  `clang-tidy`.
- `#ifdef` is followed by `#elif <value>` which evaluates to `0`.

Solution:
- Add missing includes.
- Change to `#elif defined(<value>)`.

d89582880e Kernel: Switch singletons to use new Singleton class
MemoryManager cannot use the Singleton class because
MemoryManager::initialize is called before the global constructors
are run. That caused the Singleton to be re-initialized, causing
it to create another MemoryManager instance.

Fixes #3226
