SpirvShader: Decouple SPIR-V type attributes from object representation

StorageClass, sizeInComponents, isBuiltInBlock are all attributes of the Type, not the Object.

Add 'type' field to Object so type information can easily be looked up regardless of definition opcode.

Add 'element' field to Type, simplifying the likes of WalkAccessChain.

Fixes the weird edge case of OpVariable's sizeInComponents being the size of the pointee, not its type (the pointer).
