Seperate shader

[QuantumEntangledAndy]

This attempts to seperate Shaders from Pipelines

It also removes the need to cleanup shaders from the renderer

Note: There is now 1 pipeline instance per Pipeline object, need to see what impact that has

Just a head's up of what sort of things I am working on

• Have generic trait for Buffer/Textures/Meshs this allows arbitary structures to represent a buffer
  • Instead of this:

    let proj_view = globals.get::<ProjView>().unwrap();
    // Later
    Binding::Uniform("label", Stage::All, &proj_view.buffer),

  • It becomes

    let proj_view = globals.get::<ProjView>().unwrap();
    // Later
    Binding::Uniform("label", Stage::All, &proj_view),

    SInce ProjView will have the trait saying it provides a Buffer

• Allow binding Asset or Id this is done by binding to a trait sort of like Into<Buffer> but needing a ref to Assets too
• Handle reloadable Assets, have assets track what they depend on and decide if they need to rebind/update if when of their dependencies need a rebind
• Move most boilerplate code for a render/compute into the actual draw call reducing code in user land

I have most of this already implemented in a seperate branch but I will be merging it in stages
