Latte+GL+VK: Improve handling of gfx pack texture overwrite format

Browse Source 
Graphic packs can overwrite the format of a texture (e.g. for higher bitdepth to lessen banding) but the code for this wasn't correctly working anymore.

- Fixes overwrite format being ignored for texture views on Vulkan backend
- Fixes overwrite format not being used for texture views on OpenGL

Format aliasing is complicated enough as it is, even without overwrites, so this adds a new rule to make behavior more well defined: If two textures share memory but only one uses an overwrite format, then they are no longer synchronized and are considered separate textures.

Bonus fixes for OpenGL:
- Use fbo 0 instead of -1 as the default. This silences some warnings in debug output
- On OpenGL, bind new framebuffers on handle generation so they are considered created
