Kernel/Threading: Warn when a thread can be scheduled in the Syscore (Core 1)

fixup simple type conversions where possible

HLE/Applets: Use the correct size for the framebuffer SharedMemory

We do not currently implement any cores other than the AppCore (Core 0).

AudioCore: SDL2 Sink

HLE/Applets: Use the correct size for the framebuffer SharedMemory in the swkbd and MiiSelector applets.

Move glad initialisation to the frontend

fix loader: return proper result

On SDL2 this allows it to use SDL_GL_GetProcAddress() instead of the
default function loader, and fixes a crash when using apitrace with an
EGL context.

On Qt we will need to migrate from QGLWidget to QOpenGLWidget and
QOpenGLContext before we can use gladLoadGLLoader() instead of
gladLoadGL(), since the former doesn’t expose a function loader.
