Use vector outputs for texture operations (#3939)

Browse source 
* 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
