Adds a new (and first) kind of fact to the fact manager, which is that a specific uniform value is guaranteed to be equal to a specific constant. The point of this is that such information (if known to be true by some external source) can be used by spirv-fuzz to transform the module in interesting ways that a static compiler cannot reverse via compile-time analysis. This change introduces protobuf messages for the fact, and adds capabilities to the fact manager to store this kind of fact and provide information about it.
