Add constant == uniform facts. (#2660) 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.

Represent uniform facts via descriptor set and binding. (#2681) * Represent uniform facts via descriptor set and binding. Previously uniform facts were expressed with resepect to the id of a uniform variable. Describing them with respect to a descriptor set and binding is more convenient from the point of view of expressing facts about a shader without requiring analysis of its SPIR-V. * Fix equality testing for uniform buffer element descriptors. The equality test now checks that the lengths of the index vectors match. Added a test that exposes the previous omission.

Add 'copy object' transformation (#2766) This transformation can introduce an instruction that uses OpCopyObject to make a copy of some other result id. This change introduces the transformation, but does not yet introduce a fuzzer pass to actually apply it.
