[flang][NFC] Add pointer dummy arguments tests

[clementval]

Summary

This patch adds test for calls with POINTER dummy arguments on the caller side.

It also fixes some formatting error that was introduced when upstreaming
the other pointer tests.

This patch is part of the upstreaming effort from fir-dev branch.

[PeteSteinfeld]

All builds and tests correctly and looks good.
