Applications can request the kernel to allocate a piece of the linear heap for them when creating a shared memory object.
Shared memory areas are now properly mapped into the target processes when calling svcMapMemoryBlock.

Removed the APT Shared Font hack as it is no longer needed.

R0 is used as the last parameter instead of R4.

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

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

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.

This has been entirely superseded by MicroProfile. The rest of the code
can go when a simpler frametime/FPS meter is added to the GUI.

* Make Citra build with MICROPROFILE_ENABLED set to 0

* Buildfix with microprofile kept on

* moc did not like a dialog to conditionally exist.

* Cleanup

* Fix end of line

Don't keep base_address in the loader, it doesn't belong there (with it, the loader can't be cached).

Preparation for a similar concept to Dolphin or PPSSPP. These can be JIT-ed and cached.
