bunnei a493ab2678 hle: kernel: Remove service thread manager and use weak_ptr.
- We no longer need to queue up service threads to be destroyed.
- Fixes a race condition where a thread could be destroyed too early, which caused a crash in Pokemon Sword/Shield.

bunnei 27ce97fd42 hle: kernel: Refactor to allocate a ServiceThread per service handler.
- Previously, we would allocate a thread per session, which adds new threads on CloneCurrentObject.
- This results in race conditions with N sessions queuing requests to the same service interface.
- Fixes Pokken Tournament DX crashes/softlocks, which were regressed by #6347.

Lioncash da7be67daf ipc_helpers: Remove usage of the global system instance
Resolves numerous deprecation warnings throughout the codebase due to
inclusion of this header. Now building core should be significantly less
noisy (and also relying on less global state).

This also uncovered quite a few modules that were relying on indirect
includes, which have also been fixed.

ipc: Allow all trivially copyable objects to be passed directly into WriteBuffer (#4465)
* ipc: Allow all trivially copyable objects to be passed directly into WriteBuffer

With the support of C++20, we can use concepts to deduce if a type is an STL container or not.

* More agressive concept for stl containers

* Add -fconcepts

* Move to common namespace

* Add Common::IsBaseOf

Lioncash 77356731a9 hle_ipc: Remove std::size_t casts where applicable
These were added in the change that enabled -Wextra on linux builds so
as not to introduce interface changes in the same change as a
build-system flag addition.

Now that the flags are enabled, we can freely change the interface to
make these unnecessary.

Weiyi Wang 8d6342384b HLE/IPC: HLEContext can memorize the client thread and use it for SleepClientThread
This reduces the boilerplate that services have to write out the current thread explicitly. Using current thread instead of client thread is also semantically incorrect, and will be a problem when we implement multicore (at which time there will be multiple current threads)

Lioncash fbb82e61e3 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).

Lioncash 02bc9e9de1 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).

Lioncash 0cc347462d hle_ipc: Make GetDomainMessageHeader return a regular pointer
Nothing requires the shared owner ship here, so we can just return a
plain pointer.

Lioncash 90a981a03a kernel/process: Make the handle table per-process
In the kernel, there isn't a singular handle table that everything gets
tossed into or used, rather, each process gets its own handle table that
it uses. This currently isn't an issue for us, since we only execute one
process at the moment, but we may as well get this out of the way so
it's not a headache later on.

General moving to keep kernel object types separate from the direct
kernel code. Also essentially a preliminary cleanup before eliminating
global kernel state in the kernel code.

Lioncash ff500a7b68 hle_ipc: Introduce generic WriteBuffer overload for multiple container types
This introduces a slightly more generic variant of WriteBuffer().
Notably, this variant doesn't constrain the arguments to only accepting
std::vector instances. It accepts whatever adheres to the
ContiguousContainer concept in the C++ standard library.

This essentially means, std::array, std::string, and std::vector can be
used directly with this interface. The interface no longer forces you to
solely use containers that dynamically allocate.

To ensure our overloads play nice with one another, we only enable the
container-based WriteBuffer if the argument is not a pointer, otherwise
we fall back to the pointer-based one.
