  -----------
  [flang][openacc] Allow open acc routines from other modules. (#136012)

OpenACC routines annotations in separate compilation units currently get
ignored, which leads to errors in compilation. There are two reason for
currently ignoring open acc routine information and this PR is
addressing both.
- The module file reader doesn't read back in openacc directives from
module files.
  - Simple fix in `flang/lib/Semantics/mod-file.cpp`
- The lowering to HLFIR doesn't generate routine directives for symbols
imported from other modules that are openacc routines.
- This is the majority of this diff, and is address by the changes that
start in `flang/lib/Lower/CallInterface.cpp`.
