spirv-fuzz: better computation of data synonym facts (#3010)
When a data synonym fact about two composites is added, data synonym
facts between all sub-components of the composites are also added.

Furthermore, when data synonym facts been all sub-components of two
composites are known, a data synonym fact relating the two composites
is added. Identification of this case is done in a lazy manner, when
questions about data synonym facts are asked.

The change introduces helper methods to get the size of an array type
and the number of elements of a struct type, and fixes
TransformationCompositeExtract to invalidate analyses appropriately.
