Use vector outputs for texture operations (#3939)
* Change AggregateType to include vector type counts * Replace VariableType uses with AggregateType and delete VariableType * Support new local vector types on SPIR-V and GLSL * Start using vector outputs for texture operations * Use vectors on more texture operations * Use vector output for ImageLoad operations * Replace all uses of single destination texture constructors with multi destination ones * Update textureGatherOffsets replacement to split vector operations * Shader cache version bump Co-authored-by: Ac_K <Acoustik666@gmail.com>
