Andreas Kling 11eee67b85 Kernel: Make self-contained locking smart pointers their own classes
Until now, our kernel has reimplemented a number of AK classes to
provide automatic internal locking:

- RefPtr
- NonnullRefPtr
- WeakPtr
- Weakable

This patch renames the Kernel classes so that they can coexist with
the original AK classes:

- RefPtr => LockRefPtr
- NonnullRefPtr => NonnullLockRefPtr
- WeakPtr => LockWeakPtr
- Weakable => LockWeakable

The goal here is to eventually get rid of the Lock* classes in favor of
using external locking.

sin-ack 3f3f45580a Everywhere: Add sv suffix to strings relying on StringView(char const*)
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).

No functional changes.

Brian Gianforcaro 6b85b358f8 Kernel: Unify Kernel task names for consistency
This change unifies the naming convention for kernel tasks.

The goal of this change is to:

- Make the task names more descriptive, so users can more
  easily understand their purpose in System Monitor.

- Unify the naming convention so they are consistent.

Brian Gianforcaro 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.

Ben Wiederhake 2b6546c40a Kernel: Make Thread use AK::Time internally
This commit is very invasive, because Thread likes to take a pointer and write
to it. This means that translating between timespec/timeval/Time would have been
more difficult than just changing everything that hands a raw pointer to Thread,
in bulk.

asynts 938e5c7719 Everywhere: Replace a bundle of dbg with dbgln.
These changes are arbitrarily divided into multiple commits to make it
easier to find potentially introduced bugs with git bisect.Everything:

The modifications in this commit were automatically made using the
following command:

    find . -name '*.cpp' -exec sed -i -E 's/dbg\(\) << ("[^"{]*");/dbgln\(\1\);/' {} \;

Tom 6cb640eeba Kernel: Move some time related code from Scheduler into TimeManagement
Use the TimerQueue to expire blocking operations, which is one less thing
the Scheduler needs to check on every iteration.

Also, add a BlockTimeout class that will automatically handle relative or
absolute timeouts as well as overriding timeouts (e.g. socket timeouts)
more consistently.

Also, rework the TimerQueue class to be able to fire events from
any processor, which requires Timer to be RefCounted. Also allow
creating id-less timers for use by blocking operations.

Tom 838d9fa251 Kernel: Make Thread refcounted
Similar to Process, we need to make Thread refcounted. This will solve
problems that will appear once we schedule threads on more than one
processor. This allows us to hold onto threads without necessarily
holding the scheduler lock for the entire duration.

Tom fb41d89384 Kernel: Implement software context switching and Processor structure
Moving certain globals into a new Processor structure for
each CPU allows us to eventually run an instance of the
scheduler on each CPU.

Andreas Kling a066dd1fac Kernel: Move sync and finalization tasks into their own files
Instead of clogging up the initialization sequence, put these tasks
