None of these files are used in any meaningful way. They're just
leftovers from citra. Also has the benefit of getting rid of an unused
global variable.

- This is necessary so streams are created on the same thread.

* Virtual Filesystem

* Fix delete bug and documentate

* Review fixes + other stuff

* Fix puyo regression

This makes it a compilation error to construct additional instances of
the System class directly, preventing accidental wasteful constructions
over and over.

This would result in a lot of allocations and related object
construction, just to toss it all away immediately after the call.

These are definitely not intentional, and it was intended that all of
these should have been accessing the static function GetInstance()
through the name itself, not constructed instances.

This reverts commit 77c684c1.

* Guess 'main' to be Directory by filename

LOG_GENERIC usages will be amended in a follow-up to keep API changes separate from
interface changes, as it will require removing a parameter from the relevant function
in the VMManager class.

Converts the service manager from a global into an instance-based
variable.

* core, main.h: Abort on 32Bit ROMs

* main.cpp: Fix Grammar

Also moved the GPU MemoryManager class to video_core since it makes more sense for it to be there.
