Performs type conversion from an arbitrary input type to a type that is expressed by a QuantizedType.
This handles cases where the inputType is a supported primitive type (i.e. f32, bf16, etc) or a vector/tensor type based on a supported elemental type.
Since conversion often involves introspecting some attributes of the input type in order to determine how to represent it, this is a two step process.
