Some transformations (e.g. TransformationAddFunction) rely on running the validator to decide whether the transformation is applicable. A recent change allowed spirv-fuzz to take validator options, to cater for the case where a module should be considered valid under particular conditions. However, validation during the checking of transformations had no access to these validator options. This change introduced TransformationContext, which currently consists of a fact manager and a set of validator options, but could in the future have other fields corresponding to other objects that it is useful to have access to when applying transformations. Now, instead of checking and applying transformations in the context of a FactManager, a TransformationContext is used. This gives access to the fact manager as before, and also access to the validator options when they are needed.
