The runtime was requiring that STATUS='OLD' be explicitly specified
on an OPEN statement for a connected unit. There error should issue
only if a STATUS= other than 'OLD' is specified; an OPEN with no
STATUS= specifier is okay.

Add new unit tests for external Fortran I/O that drive the
Fortran I/O runtime API from C++ and exercise basic writing
and read-back in the various combinations of access modes,
record length variability, and formatting. Sequential modes
are tested with positioning. More thorough tests written in
Fortran will follow when they can be compiled and run.
The Fortran runtime's error termination callback registration
was extended with source file and line number positions for
better failure messages in unit testing.

This change prepares usage of lipgmath description in lowering.
- Removes the static variable templates that were used to abstract
libpgmath description
- Move the description to pgmath.h.inc header and rework the macros
so that they can both be used to declare pgmath functions and use
them.
The way they are to be used is left to pgmath.h.inc user that
must define PGMATH_USE_XX macros that will be called for all pgmath
functions in pgmath.h.inc.
- In intrinsic-library.cpp define PGMATH_USE_XX macro callbacks in
order to capture function pointers to pgmath functions as well as
a description of their type. This will be used for constant folding
using pgmath.
- Change atan/atan2 handling to use atan2 instead of atan when there are two
arguments because it is easier to handle in the runtime description.
Also fixes lipgmath linking regression after D78215 cmake changes.
This change is motivated by the need to use a similar pgmath
description in lowering. The difference is that no function pointers will
be taken there, and instead only the function name and type are needed.
