ee405335 - DiagnosticInfo: Fix stack-use-after-scope in DiagnosticInfoStackSize (#190442)

DiagnosticInfo: Fix stack-use-after-scope in DiagnosticInfoStackSize (#190442) The string literal "stack frame size" passed to the base class constructor created a temporary Twine that was destroyed after the base constructor completed, leaving a dangling reference. Fix by storing the Twine as a member variable in the derived class, ensuring it lives as long as the diagnostic object itself.
