[clang][ASTImporter][StructuralEquivalence] improve StructuralEquival…
8612730 
…ence on recordType (#76226)

Types comparison in `StructuralEquivalence` ignores its `DeclContext`
when they are generated by template specialization implicitly and this
will produce incorrect result. Add comparison of `DeclContext` of
ClassTemplateSpecializationDecl to improve result.
fix [issue](#65913)
