[cxx-interop][LLDB] Update test for variadic templates, part 1

C++ class template instantiations previously did not get a valid generated Swift type name if they used variadic generics.

See swiftlang/swift#77450.

Since fully enabling the test requires the Swift PR to be merged, and the Swift PR relies on this test passing, this PR temporarily disables the failing asserts.
