cfb327a85b kernel/thread: Migrate WaitCurrentThread_Sleep into the Thread interface
Rather than make a global accessor for this sort of thing. We can make
it a part of the thread interface itself. This allows getting rid of a
hidden global accessor in the kernel code.

f68087ce12 kernel/thread: Amend condition within UpdatePriority()
This condition was checking against the nominal thread priority, whereas
the kernel itself checks against the current priority instead. We were
also assigning the nominal priority, when we should be assigning
current_priority, which takes priority inheritance into account.

This can lead to the incorrect priority being assigned to a thread.

Given we recursively update the relevant threads, we don't need to go
through the whole mutex waiter list. This matches what the kernel does
as well (only accessing the first entry within the waiting list).

8b4380a068 kernel/thread: Maintain priority ordering of added mutex waiting threads
The kernel keeps the internal waiting list ordered by priority. This is

Makes it an instantiable class like it is in the actual kernel. This

change, now that we can encapsulate a reference to the system instance
in the class.

4ed697697d core/hle/kernel: Split transfer memory handling out into its own class
Within the kernel, shared memory and transfer memory facilities exist as
completely different kernel objects. They also have different validity
checking as well. Therefore, we shouldn't be treating the two as the
same kind of memory.

They also differ in terms of their behavioral aspect as well. Shared
memory is intended for sharing memory between processes, while transfer
memory is intended to be for transferring memory to other processes.

This breaks out the handling for transfer memory into its own class and
treats it as its own kernel object. This is also important when we
consider resource limits as well. Particularly because transfer memory
is limited by the resource limit value set for it.

While we currently don't handle resource limit testing against objects
yet (but we do allow setting them), this will make implementing that
behavior much easier in the future, as we don't need to distinguish
between shared memory and transfer memory allocations in the same place.

9c8de2ee40 kernel/server_port: Make data members private
With this, all kernel objects finally have all of their data members
behind an interface, making it nicer to reason about interactions with
other code (as external code no longer has the freedom to totally alter
internals and potentially messing up invariants).

922f4d460e kernel/hle_ipc: Convert std::shared_ptr IPC header instances to std::optional
There's no real need to use a shared lifetime here, since we don't
actually expose them to anything else. This is also kind of an
unnecessary use of the heap given the objects themselves are so small;
small enough, in fact that changing over to optionals actually reduces
the overall size of the HLERequestContext struct (818 bytes to 808
bytes).

1f5cd8cac7 kernel: Make the address arbiter instance per-process
Now that we have the address arbiter extracted to its own class, we can
fix an innaccuracy with the kernel. Said inaccuracy being that there
isn't only one address arbiter. Each process instance contains its own
AddressArbiter instance in the actual kernel.

This fixes that and gets rid of another long-standing issue that could
arise when attempting to create more than one process.

0321c000ee kernel/svc: Move address arbiter signaling behind a unified API function
Similar to how WaitForAddress was isolated to its own function, we can
also move the necessary conditional checking into the address arbiter
class itself, allowing us to hide the implementation details of it from
public use.

7a518ea8fd kernel/svc: Move address arbiter waiting behind a unified API function
Rather than let the service call itself work out which function is the
proper one to call, we can make that a behavior of the arbiter itself,
so we don't need to directly expose those implementation details.

7d25f9a4a2 core/hle/ipc: Remove unnecessary includes
Removes a few inclusion dependencies from the headers or replaces
existing ones with ones that don't indirectly include the required
headers.

This allows removing an inclusion of core/memory.h, meaning that if the
memory header is ever changed in the future, it won't result in
rebuilding the entirety of the HLE services (as the IPC headers are used
quite ubiquitously throughout the HLE service implementations).
