VideoCore: Unify interface to OpenGL and SW rasterizers This removes explicit checks sprinkled all over the codebase to instead just have the SW rasterizer expose an implementation with no-ops for most operations.

video_core/engines: Remove unnecessary includes Removes a few unnecessary dependencies on core-related machinery, such as the core.h and memory.h, which reduces the amount of rebuilding necessary if those files change. This also uncovered some indirect dependencies within other source files. This also fixes those.

common: Move settings to common from core. - Removes a dependency on core and input_common from common.

video_core: Make global EmuWindow instance part of the base renderer class Makes the global a member of the RendererBase class. We also change this to be a reference. Passing any form of null pointer to these functions is incorrect entirely, especially given the code itself assumes that the pointer would always be in a valid state. This also makes it easier to follow the lifecycle of instances being used, as we explicitly interact the renderer with the rasterizer, rather than it just operating on a global pointer.

video_core: Eliminate the g_renderer global variable We move the initialization of the renderer to the core class, while keeping the creation of it and any other specifics in video_core. This way we can ensure that the renderer is initialized and doesn't give unfettered access to the renderer. This also makes dependencies on types more explicit. For example, the GPU class doesn't need to depend on the existence of a renderer, it only needs to care about whether or not it has a rasterizer, but since it was accessing the global variable, it was also making the renderer a part of its dependency chain. By adjusting the interface, we can get rid of this dependency.
