  [flang] Skip `Fortran STOP:` before message when NO_STOP_MESSAGE is set

In 'STOP bye bye', do not print 'Fortran STOP:` before 'bye bye' when
NO_STOP_MESSAGE environment variable is set at runtime.

Also only exit with code 1 in StopStatementText if this is an ERROR STOP.
This matches other compiler behaviors.

Move STOP related unit tests in their own test file and add new tests to
cover this change.
