EEVEE: Port existing EEVEE shaders and generated materials to use GPUShaderCreateInfo.

Required by Metal backend for efficient shader compilation. EEVEE material
resource binding permutations now controlled via CreateInfo and selected
based on material options. Other existing CreateInfo's also modified to
ensure explicitness for depth-writing mode. Other missing bindings also
addressed to ensure full compliance with the Metal backend.
