[flang] Add atomic_fetch_or to the list of intrinsics

Add the atomic subroutine, atomic_fetch_or, to the list of
intrinsic subroutines. Add new enumerators to deal with the rank
of the atom dummy argument, and the kind of atomic_int_kind. Use
check for a coindexed-object for the fourth dummy argument. Move
atomic_int_kind and atomic_logical_kind definitions from
iso_fortran_env module to the __fortran_builtins module to allow
for access to those values when analyzing `atomic_fetch_or`
calls in flang/lib/Evaluate/intrinsics.cpp.
