fixup! [clang][ssaf] Implement JSON format for CallGraph summary

The order of checks were unspecified in the test.
Consequently, "polymorphic" may have appeared before "caller" failing the test.

This patch splits the test into separate files so these wouldn't interfere.

Example bot failures:

Fixes up #189681
