Miscallenious fixes to gl backend and qt frontend (#6834)

* 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
