No more context mess (#1531)

* WIP: use Duckstation's context code to directly render into QT Widget from separate thread without two OpenGL contexts

currently only works on Windows

* reenable gay OSD

* add back vsync

* make it atleast a little more thread safe

* linux support

* don't segfault on closing

* reorganise and cleanup build system
it's still not good, but better than before

* macos?

* try to get it working on Ubuntu CI
also update instructions

* let's try this

* ok how about this

* try creating an OGL 4.3 context first
(https://i.kym-cdn.com/photos/images/original/001/264/842/220.png)

* fix Ubuntu

* hm

* try again for Windows

* let's try this

* make the OpenGL renderer work again
that was stupid

* do OGL surface resizing from the mainthread

* Fix small mistake in GL context creation on macOS causing version 3.2 to
be considered invalid

* C stupidness

* cleanup

* don't let the emuthread deinit OGL if there's no OGL

* reset lastScreenWidth/Height when deiniting OpenGL

* disable stencil test while drawing framebuffers

* macOS: Link Cocoa framework explicitly when not building with Qt6

Seems to be needed for the classes used by DuckStation's GL context
code.

* Set ScreenPanelGL's minimum size immediately

Fixes GL context creation for OpenGL display on macOS using the wrong
size as the underlying window was not resized to the correct size by Qt
yet.

* don't emit window updates when OGL display is used

* stuff Arisotura said
