Frontend PR fixes (#6378)

Browse Source 
* citra_qt: Check if renderer is null

* core: Fix dynarmic use-after-free error

* bootmanager: Add current context check in DoneCurrent

* Loading a save state would destroy the frame dumper class, which contains a shared context. That context would call DoneCurrent without checking if it was actually bound or not, resulting in crashes when calling opengl functions

* externals: Correct glad readme

* common: Log renderer debug setting

* citra: Make lambda lower case

* Consistency with review comments on the PR

* video_core: Kill more global state

* GetResolutionScaleFactor would be called somewhere in the renderer constructor chain but it relies on the yet unitialized g_renderer, resulting in crashes when the resolution scale is set to auto. Rather than adding a workaround, let's kill this global state to fix this for good
