Lioncash 3f08e8d8d4 core/memory: Migrate over GetPointer()
With all of the interfaces ready for migration, it's trivial to migrate
over GetPointer().

Lioncash 536fc7f0ea core: Prepare various classes for memory read/write migration
Amends a few interfaces to be able to handle the migration over to the
new Memory class by passing the class by reference as a function
parameter where necessary.

Notably, within the filesystem services, this eliminates two ReadBlock()
calls by using the helper functions of HLERequestContext to do that for
us.

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 08d507a196 kernel/server_session: Remove obsolete TODOs
These are holdovers from Citra.

Lioncash 7a7ffa602d kernel/server_session: Return a std::pair from CreateSessionPair()
Keeps the return type consistent with the function name. While we're at
it, we can also reduce the amount of boilerplate involved with handling
these by using structured bindings.

Lioncash 20cc0b8d3c kernel/wait_object: Make ShouldWait() take thread members by pointer-to-const
Given this is intended as a querying function, it doesn't make sense to
allow the implementer to modify the state of the given thread.

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 221613d4ea kernel/server_session: Make data members private
Makes it much nicer to locally reason about server session behavior, as
part of its functionality isn't placed around other classes.

Lioncash 1f0c8bfeda core/kernel: Remove unnecessary inclusions
Gets rid of a few unnecessary header dependencies in some source files.

Lioncash 6383653a8d hle_ipc: Add member function for querying the existence of a domain header
Gets rid of the need to call the getter and then check for null.

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.

Lioncash baed7e1fba kernel/thread: Make all instance variables private
Many of the member variables of the thread class aren't even used
outside of the class itself, so there's no need to make those variables
public. This change follows in the steps of the previous changes that
made other kernel types' members private.

The main motivation behind this is that the Thread class will likely
change in the future as emulation becomes more accurate, and letting
random bits of the emulator access data members of the Thread class
directly makes it a pain to shuffle around and/or modify internals.
Having all data members public like this also makes it difficult to
reason about certain bits of behavior without first verifying what parts
of the core actually use them.

Everything being public also generally follows the tendency for changes
to be introduced in completely different translation units that would
otherwise be better introduced as an addition to the Thread class'
public interface.

Lioncash 4a587b81b2 core/core: Replace includes with forward declarations where applicable
The follow-up to e2457418da, which
replaces most of the includes in the core header with forward declarations.

This makes it so that if any of the headers the core header was
previously including change, then no one will need to rebuild the bulk
of the core, due to core.h being quite a prevalent inclusion.

This should make turnaround for changes much faster for developers.

Lioncash 0cbcd6ec9a kernel: Eliminate kernel global state
As means to pave the way for getting rid of global state within core,
This eliminates kernel global state by removing all globals. Instead
this introduces a KernelCore class which acts as a kernel instance. This
instance lives in the System class, which keeps its lifetime contained
to the lifetime of the System class.

This also forces the kernel types to actually interact with the main
kernel instance itself instead of having transient kernel state placed
all over several translation units, keeping everything together. It also
has a nice consequence of making dependencies much more explicit.

This also makes our initialization a tad bit more correct. Previously we
were creating a kernel process before the actual kernel was initialized,
which doesn't really make much sense.

The KernelCore class itself follows the PImpl idiom, which allows
keeping all the implementation details sealed away from everything else,
which forces the use of the exposed API and allows us to avoid any
unnecessary inclusions within the main kernel header.

Lioncash aac5792a2b kernel/server_session: Add IsSession() member function
Allows querying the inverse of IsDomain() to make things more readable.
This will likely also be usable in the event of implementing
ConvertDomainToSession().

Lioncash da2f00ab7d client_port: Make all data members private
These members don't need to be entirely exposed, we can instead expose
an API to operate on them without directly needing to mutate them

We can also guard against overflow/API misuse this way as well, given
active_sessions is an unsigned value.

Lioncash a2304fad16 kernel: Remove unnecessary includes
Removes unnecessary direct dependencies in some headers and also gets
rid of indirect dependencies that were being relied on to be included.

Lioncash dbfe82773d thread: Convert ThreadStatus into an enum class
Makes the thread status strongly typed, so implicit conversions can't
happen. It also makes it easier to catch mistakes at compile time.

Lioncash 7c9644646f
general: Make formatting of logged hex values more straightforward
This makes the formatting expectations more obvious (e.g. any zero padding specified
is padding that's entirely dedicated to the value being printed, not any pretty-printing
that also gets tacked on).

Subv 94ee8fc97b Kernel/IPC: Add a small delay after each SyncRequest to prevent thread starvation.
Ported from citra PR #3091

The delay specified here is from a Nintendo 3DS, and should be measured in a Nintendo Switch.

This change is enough to prevent Puyo Puyo Tetris's main thread starvation.
