- Rework the host runtime table so that it is constexpr to avoid
having to construct it and to store/propagate it.
- Make the interface simpler (remove many templates and a file)
- Enable 16bits float folding using 32bits float host runtime
- Move StaticMultimapView into its own header to use it for host
folding

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.
