* renderer_gl: Make rasterizer normal class member
* It doesn't need to be heap allocated anymore
* gl_rasterizer: Remove default_texture
* It's unused
* gl_rasterizer: General cleanup
* gl_rasterizer: Lower case lambdas
* Match style with review comments from vulkan backend
* rasterizer_cache: Prevent memory leak
* Since the switch from shared_ptr these surfaces were no longer being destroyed properly. Use our garbage collector for that purpose to destroy it safely for both backends
* rasterizer_cache: Make temp copy of old surface
* The custom surface would override the memory region of the old region resulting in garbage data, this ensures the custom surface is constructed correctly
* citra_qt: Manually create dialog tabs
* Allows for custom constructors which is very useful. While at it, global state is now eliminated from configuration
* citra_qt: Eliminate global system usage
* core: Remove global system usage in memory and HIO
* citra_qt: Use qOverload
* tests: Run clang format
* gl_texture_runtime: Fix surface scaling
* Forward declare ui and use unique_ptr
* ConfigureEnhancements: use unique_ptr for ui
* Use make_unique instead of new where applicable
* Move some of the ui includes that already used unique_ptr
* main.cpp: also make use of make_unique on Config
* Address review comments
