  [Flang] mark safe external globals as dso_local (#189709)

Globals inside a Fortran module are not marked as dso_local,
which results in their alignment not being promoted.
This fix mimics some of the functionality found in
shouldAssumeDSOLocal in /clang/lib/CIR/CodeGen/CIRGenModule.cpp

Fixes #189069
