spirv-fuzz: Support pointer types in FuzzerPassAddParameters (#3627)
For FuzzerPassAddParameters, adds pointer types (that have the storage class Function or Private) to the pool of available types for new parameters. If there are no variables of the chosen pointer type, it invokes TransformationAddLocalVariable / TransformationAddGlobalVariable to add one. Part of #3403
