tldr: Adds a test to verify GCC's handling of `[[clang::no_specializations]]` on template declarations, ensuring it correctly diagnoses specializations.

This commit introduces a new test case to the GCC test suite. The test verifies the compiler’s behavior with the [[clang::no_specializations]] attribute when applied to a template declaration followed by a primary template definition without the attribute. It ensures that GCC, like Clang (which is being fixed), correctly diagnoses any subsequent explicit or partial specializations, preventing regressions in this area.
