  -----------
  [Flang] enable fir.is_present and fir.absent with function types

Fortran dummy procedures and procedure pointer can be OPTIONAL, and
there is no technical reason to prevent fir.is_present and
fir.absent from accepting function types, so allow it and add test.

Note: This is part of upstreaming from the fir-dev branch of
https://github.com/flang-compiler/f18-llvm-project. This patch is
basically upstreaming the following PR.
