* [Dependency] source generator
No more reflection, no more codegen at runtime
Also various changes to Roslyn helpers to make this easier to write.
Requires all types with dependencies to be partial and not have readonly dependency fields. An analyzer enforces this at warning level, the previous injection strategies have remained in the code *for now* as a fallback.
No fallback is available for [field: Dependency] properties, due to a Roslyn bug.
Code Fixes exist. We love Roslyn
* Apply dependencies generator changes to all code
* Release notes
* Preprocessor got hands
* Handle nullable dependencies
These are bad but gotta deal with it.
* Apply suggestions from code review

This is a far cry from a proper resource tracking system, but it's something to avoid a ton of otherwise-unused parallax textures being loaded at game start and consuming VRAM.
This allows huge textures (e.g. Ratvar) to be removed from the meta-atlas. This saves a significant chunk of VRAM from the meta atlas in SS14 (~126 MB) which might help a bit with low-VRAM systems.
Many patterns (both in engine and content) make use of regular TryGetResource returning null. The problem is that if the resource doesn't exist, it won't be cached and the code attempts to load it from disk *every single time*.
For example, opening an inventory in SS14 would hang the client for ages on some UI themes due to the UITheme texture fallback system constantly trying to load a texture that doesn't exist.
* Add load parameter support to RSIs.
Currently only supports turning sRGB off. RSIs with custom load parameters are not thrown into the meta-atlas.
As part of this, TextureLoadParameters and TextureSampleParameters has been made to support equality.
* Add UV2 channel to vertices.
This is a bad hack to make displacement maps work in Robust. The UV2 channel goes from 0 -> 1 across the draw and can therefore be used by displacement maps to map a separate displacement map layer on top of the regular meta-atlas RSI texture.
This creates float inaccuracy issues but they weren't bad enough to completely void the feature. I'm thinking I learn from this experience and completely re-do how UVs work with the renderer rewrite, so that hopefully won't happen anymore.
This required dumping the optimized PadVerticesV2 because the changed struct size made it impractical. RIP.
I don't like this approach at all but the renderer is slated for a rewrite anyways, and all shaders will need to be rewritten regardless.
* Add CopyToShaderParameters for sprite layers.
This effectively allows copying the parameters of a sprite layer into another layer's shader parameters. The use case is to copy texture coordinates for displacement maps, as the exact map used changes depending on orientation. It also enables animations to be used though I didn't use that personally.
