[clang-repl] Additional test for disambiguation of templates

[Hahnfeld]

Summary

This test case was fixed in commit rG2c4620c1 ("Consider the scope spec in template lookups for deduction guides."), but it is worth having a dedicated test case with a templated struct and a using declaration.

Thanks, @Hahnfeld!

It might be a good idea to add this test to disambiguate-decl-stmt.cpp where we track these things.
