Avalonia - Couple fixes and improvements to vulkan (#3483)
* drop split devices, rebase

* add fallback to opengl if vulkan is not available

* addressed review

* ensure present image references are incremented and decremented when necessary

* allow changing vsync for vulkan

* fix screenshot on avalonia vulkan

* save favorite when toggled

* improve sync between popups

* use separate devices for each new window

* fix crash when closing window

* addressed review

* don't create the main window with immediate mode

* change skia vk delegate to method

* update vulkan throwonerror
