MakeCurrent is a costly (according to Nsight's profiler it takes a tenth
of a millisecond to complete), and we don't have a reason to call it
because:
- Qt no longer signals a warning if it's not called
- yuzu no longer supports macOS

This was carried from Citra and wasn't really used on yuzu. It also adds
some runtime overhead. This commit removes it from yuzu's codebase.

With all of the trivial parts of the memory interface moved over, we can
get right into moving over the bits that are used.

Note that this does require the use of GetInstance from the global
system instance to be used within hle_ipc.cpp and the gdbstub. This is
fine for the time being, as they both already rely on the global system
instance in other functions. These will be removed in a change directed
at both of these respectively.

For now, it's sufficient, as it still accomplishes the goal of
de-globalizing the memory code.

* kernel: Replace usage of boost::intrusive_ptr with std::shared_ptr for kernel objects.

Emulates negative y viewports with ARB_clip_control. This allows us to
more easily emulated pipelines with tessellation and/or geometry shader
stages. It also avoids corrupting games with transform feedbacks and
negative viewports (gl_Position.y was being modified).

- This does not actually seem to exist in the real kernel - games reset these automatically.

These two colorful themes are based on the Default and Dark themes, and contain icons that are colored rather than black and white. These icons come from icons8.com and they have been slightly revised by me. I'm pretty sure I was licensed to use them for Citra.

Spit out a LOG_INFO of the current game name and it's title id in the log. This helps to read log files and figure out which games have which issues

The speed limiter being a frame limiter is an implmentation detail and can be changed in the future. What user care about is that it limit the emulation speed in genenral (not just graphics but also audio+input)
