  [flang][runtime] Support READ after WRITE w/o positioning (#74650)

Most Fortran implementations support a READ statement after a WRITE
without repositioning on a sequential unit; it implies on ENDFILE and
then hits an EOF condition.

Fixes llvm-test-suite/Fortran/gfortran/regression/backspace_2.f.
