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.
