Cart refactor (#1073)
complete cart-interface refactor, will make this code a lot easier to deal with

Fix edge case in the division engine, fix edge case in the CPU (#1003)
* Fixed division edge case: Div64/32 and Div64/64 set the remainder to 0 if dividend == INT64_MIN && divisor == -1

* Fixed CPU edge case where ARM9 ALU ops would switch to Thumb even when they shouldn't

* Only clear the lowest bit of the jump address in ALU ops with rd==15 (on recommendation of RSDuck)

Allow for a more modular renderer backends (#990)
* Draft GPU3D renderer modularization

* Update sources C++ standard to C++17

The top-level `CMakeLists.txt` is already using the C++17 standard.

* Move GLCompositor into class type

Some other misc fixes to push towards better modularity

* Make renderer-implementation types move-only

These types are going to be holding onto handles
of GPU-side resources and shouldn't ever be copied around.

* Fix OSX: Remove 'register' storage class specifier

`register` has been removed in C++17...
But this keyword hasn't done anything in years anyways.

OSX builds consider this "warning" an error and it
stops the whole build.

* Add RestartFrame to Renderer3D interface

* Move Accelerated property to Renderer3D interface

There are points in the code base where we do:
`renderer != 0` to know if we are feeding
an openGL renderer. Rather than that we can instead just have this be
a property of the renderer itself.
With this pattern a renderer can just say how it wants its data to come
in rather than have everyone know that they're talking to an OpenGL
renderer.

* Remove Accelerated flag from GPU

* Move 2D_Soft interface in separate header

Also make the current 2D engine an "owned" unique_ptr.

* Update alignment attribute to standard alignas

Uses standardized `alignas` rather than compiler-specific
attributes.

https://en.cppreference.com/w/cpp/language/alignas

* Fix Clang: alignas specifier

Alignment must be specified before the array to align the entire array.

https://en.cppreference.com/w/cpp/language/alignas

* Converted Renderer3D Accelerated to variable

This flag is checked a lot during scanline rasterization. So rather
than having an expensive vtable-lookup call during mainline rendering
code, it is now a public constant bool type that is written to only once
during Renderer3D initialization.
