c0a01f3adc kernel/codeset: Make CodeSet's memory data member a regular std::vector
The use of a shared_ptr is an implementation detail of the VMManager
itself when mapping memory. Because of that, we shouldn't require all
users of the CodeSet to have to allocate the shared_ptr ahead of time.
It's intended that CodeSet simply pass in the required direct data, and
that the memory manager takes care of it from that point on.

This means we just do the shared pointer allocation in a single place,
when loading modules, as opposed to in each loader.

1cf90f4570 file_sys/patch_manager: Deduplicate NSO header
This source file was utilizing its own version of the NSO header.
Instead of keeping this around, we can have the patch manager also use
the version of the header that we have defined in loader/nso.h

90e27ea003 loader/nso: Fix definition of the NSO header struct
The total struct itself is 0x100 (256) bytes in size, so we should be
providing that amount of data.

Without the data, this can result in omitted data from the final loaded
NSO file.

1b6bd9d6df kernel: Move CodeSet structure to its own source files
Given this is utilized by the loaders, this allows avoiding inclusion of
the kernel process definitions where avoidable.

This also keeps the loading format for all executable data separate from
the kernel objects.

1abed2f4c4 kernel/process: Make CodeSet a regular non-inherited object
These only exist to ferry data into a Process instance and end up going
out of scope quite early. Because of this, we can just make it a plain
struct for holding things and just std::move it into the relevant
function. There's no need to make this inherit from the kernel's Object
type.

cf9d6c6f52 kernel/process: Make data member variables private
Makes the public interface consistent in terms of how accesses are done
on a process object. It also makes it slightly nicer to reason about the
logic of the process class, as we don't want to expose everything to
external code.

a63e6f9dfd loader: Make the Load() function take a process as a regular reference, not a SharedPtr
A process should never require being reference counted in this
situation. If the handle to a process is freed before this function is
called, it's definitely a bug with our lifetime management, so we can
put the requirement in place for the API that the process must be a
valid instance.

83377113bf memory: Dehardcode the use of fixed memory range constants
The locations of these can actually vary depending on the address space
layout, so we shouldn't be using these when determining where to map
memory or be using them as offsets for calculations. This keeps all the
memory ranges flexible and malleable based off of the virtual memory
manager instance state.

75603b005b process/vm_manager: Amend API to allow reading parameters from NPDM metadata
Rather than hard-code the address range to be 36-bit, we can derive the
parameters from supplied NPDM metadata if the supplied exectuable
supports it. This is the bare minimum necessary for this to be possible.

The following commits will rework the memory code further to adjust to
this.

2ea45fe75b kernel/thread: Include thread-related enums within the kernel namespace
Previously, these were sitting outside of the Kernel namespace, which
doesn't really make sense, given they're related to the Thread class

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.

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.

2beda7c2b3 kernel/process: Use accessors instead of class members for referencing segment array
Using member variables for referencing the segments array increases the
size of the class in memory for little benefit. The same behavior can be

segment.

We should always assume the filesystem is volatile and check each IO

- Debugging of threads should work correctly with source and assembly level stepping and modifying registers and memory, meaning threads and callstacks are fully clickable in VS.
- List of modules is available to the client, with assumption that .nro and .nso are backed up by an .elf with symbols, while deconstructed ROMs keep N names.
- Initial support for floating point registers.
