spirv-fuzz: Fix problem with instruction context (#4394)

Adds an additional validity check to ensure that every instruction's
context pointer matches the enclosing IR context. Avoids a redundant
copy constructor call in TransformationDuplicateRegionWithSelection
that was leading to a bad IR context for some instructions.

Related: #4387, #4388.
Fixes #4393.
