Passing all the rain pass configs through a giant struct into the rain shader. I've included the compute shader fields, because I have hope that the compute pass can use the same shader module.

Merged the vertex and fragment shader WGSL files, because their bindings can't collide anyhow. The rain render shader now accepts a bind group of time uniforms, which change on every frame, as well as MSDF uniforms, along with an MSDF sampler and texture that's loaded in from the PNG. The shader currently renders the correct grid of quads for volumetric mode, displays the first glyph raw in each one, and every sixty frames, turns on and off the blue channel.
