113a3972a6 core/loader: Remove dependencies on the global system instance
Now all that remains is:

18 instances in file_sys code
14 instances in GDB stub code (this can be tossed wholesale)
4 instances in HLE code
2 instances in settings code.

441a2812ed loader/nso: Resolve moves not occurring in DecompressSegment
Given the std::vector was const, an automatic move out of the function
could not occur.

We can allow automatic return value optimizations to occur by making the
buffer non-const.

5a7eecc3ad loader: provide default arguments (zero byte) to NSOs
Certain newer unity games (Terraria, Pokemon Mystery Dungeon) require
that the argument region be populated. Failure to do so results in
an integer underflow in argument count, and eventually an unmapped
read at 0x800000000. Providing this default fixes this.

Note that the behavior of official software is as yet unverified,
arguments-wise.

7e94e544f4 core/loaders: Simplify PhysicalMemory usage.
It is currently a std::vector, however we might want to replace it with a more fancy allocator.
So we can't use the C++ iterators any more.

9bede4eeed VM_Manager: Align allocated memory to 256bytes
This commit ensures that all backing memory allocated for the Guest CPU
is aligned to 256 bytes. This due to how gpu memory works and the heavy
constraints it has in the alignment of physical memory.

common/hex_util: Combine HexVectorToString() and HexArrayToString()
These can be generified together by using a concept type to designate

612e1388df core/core: Move process execution start to System's Load()
This gives us significantly more control over where in the
initialization process we start execution of the main process.

Previously we were running the main process before the CPU or GPU
threads were initialized (not good). This amends execution to start
after all of our threads are properly set up.

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.

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

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.
