* Implements hardware acceleration for SHA256 instructions.
* Adds SHA256 instructions introduced in ARMv8 to A32 frontend.
* Implements polyfill for processors that do not support hardware
accelerated SHA instructions.
Inlines implementation of exclusive instructions into JITted code,
improving performance of applications relying heavily on these
instructions.
We also fastmem these instructions for additional speed, with
support for appropriate recompilation on fastmem failure.
An unsafe optimization to disable the intercore global_monitor is also
provided, should one wish to rely solely on cmpxchg semantics for
safety.

* this resolves the todo items in the CMakeLists.txt
* a version requirement check for ffmpeg is added to catch issues early
* for future-proof reasons, nasm/yasm is now only required when build on
x86/AMD64 systems
On Linux, due to the way we include SDL2 as a submodule, it makes it
difficult for us to specify which SDL_config.h we intended to include.
Before, CMake would default to the dummy one included with SDL and
ignore the generated one.
This tells CMake to use the generated one. In addition, we define
USING_GENERATED_CONFIG_H to throw an error in case the dummy config is
used by accident. Fixes Vulkan not working on Linux yuzu-cmd.
yuzu requires CMake 3.15 yet find_program was using REQUIRED, which is
only available on 3.18 and later. Instead, we check for
"<VAR>-NOTFOUND".
In addition, check for additional requirements before building libusb or
FFmpeg with autotools. Otherwise, CMake configuration will pass yet
compilation will fail.
Fixes an issue where libusb.h wouldn't be found when building yuzu on
MSVC.
This only affects the "traditional" CMake pathway for linking libusb to
yuzu AKA MSVC. For autotools we still want to set these variables before
configuring SDL.
