* Accept `#[rust_gpu::spirv()]` attributes rather than `#[spirv()]` in backend * Implemented `#[spirv(..)]` proc macro attribute for all platforms that conditionally translates to `#[rust_gpu::spirv()]` based on platform * Changed `SpirvBuilder` to always apply `register_tool(rust_gpu)` attribute to shader crates * Updated docs * Added changelog
