  [flang] Improve error recovery for bad statement after CONTAINS (#109698)

After a CONTAINS statement in a program unit, a statement that cannot
begin a subprogram will trigger catastrophic error recovery. But the
compiler is presently emitting multiple errors for the same location
about expected variations of END statements. Emit fewer messages.

Fixes https://github.com/llvm/llvm-project/issues/109609.
