This makes it more inline with its currently unavailable standardized
analogue std::derived_from.
While we're at it, we can also make the template match the requirements
of the standardized variant as well.
This increases the PointerBufferSize as a lager one is required by some services.
This change is still not hw-accurate, but it is proven to work in Ryujinx.
Instead of using a hardcoded size, we should figure out the specific values for each service in the future. Some of them can be taken from Atmosphere: https://github.com/Atmosphere-NX/Atmosphere/search?q=PointerBufferSize.
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).
Now it also indicates the name and max session count. This also gives a
name to the unknown bool. This indicates if the created port is supposed
to be using light handles or regular handles internally. This is passed
to the respective svcCreatePort parameter internally.
These auto-deduce the result based off its arguments, so there's no need
to do that work for the compiler, plus, the function return value itself
already indicates what we're returning.
Avoids the need to create a copy of the std::string instance
(potentially allocating).
The only reason RegisterService takes its argument by value is because
it's std::moved internally.
These are needed by Edizon to boot. They are used to see if a user is using SX OS, as SX OS registers a custom service called 'tx' and attempting to register a service of the same name lets the application know if it is present.

This also moves them into the cpp file and limits the visibility to
where they're directly used. It also gets rid of unused or duplicate
error codes.
The only reason this include was necessary, was because the constructor
wasn't defaulted in the cpp file and the compiler would inline it
wherever it was used. However, given Controller is forward declared, all
those inlined constructors would see an incomplete type, causing a
compilation failure. So, we just place the constructor in the cpp file,
where it can see the complete type definition, allowing us to remove
this include.
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.
Allows querying the inverse of IsDomain() to make things more readable.
This will likely also be usable in the event of implementing
ConvertDomainToSession().
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.
