Use 1-channel font textures; glyph ranges support; vulkan image descriptors and "helper" functions
...
* To save some memory, use just 1-channel alpha-only textures
* Add some sort of wider glyph ranges support
* Chop single-ish vulkan font image uploading function into separate reusable helper functions
* Use descriptor set for ImTextureID but probably use texture array and push constants for "fast-path" if need arises
