9ef25a6beb IPC bug fixes
This fixes two bugs in IPC that were discovered when running Puyo Puyo
Tetris.

The CloneCurrentObject control IPC will now correctly return the handle
of the newly created object through move handles, rather than pushing it
as a result.

The size array of u16s with the sizes of each C buffer is now taken into
account when reading them. Before this change C buffers were entirely
broken.

a53d6266c7 Implement a basic NSP loader
An NSP (Nintendo Submission Package) is effectively a PFS0 containing
NCAs, there are also tickets and a CNMT file which contains metadata
about updates. The current implementation is very basic and only

An NCA's ExeFS can be loaded by placing each NSO sequentially into
memory, starting with rtld which will link them together.

Currently only decrypted NCAs are supported, encryption and BKTR
handling will be added at a later time.

db64f53cfb Implement filesystem backends for RomFS and Partition FS
RomFS is a hierarchial filesystem where each level is made up of a
linked list of files and child directories. It is used in NCAs to store
the applications icon as well as by applications themselves for
accessing assets.

Partition FS encapsulates both the HFS0 found in XCIs and the PFS0 used
for ExeFS images and NSPs, it is purely file based and has no support at
all for directories aside from the root.

00cdc1fd6f Refactor the memory implementation and add Regions
This commit does a major refactor of the memory implementation, it forms a memory map which is far cleaner than trying to access it through a handle table lookup. In addition, it creates a common interface for all memory kernel objects: KMemory from which all other kernel memory objects inherit. This allows doing resizing, permission change, etc without casting to the base memory type.
