Enable usage of shared pio

[ulmononian]

Description

Currently, CMakeLists.txt requires static builds of parallelio (see these lines). A relaxation of this requirement (i.e.: to allow shared or static versions of parallelio) could be facilitated by updating CMakeModules to its develop branch, where FindPIO.cmake can automatically accommodate both static or shared builds.

Apart from updating CMakeModules to develop, the STATIC requirement would need to be removed from CMakeLists.txt.

This change is in anticipation of transition from hpc-stack to spack-stack, where parallelio is currently being built as a shared library (see NOAA-EMC/spack-stack PR #454, issue #478).

RT cpld_contrl_p8 passed on Orion (Intel) and Hera (Intel & GNU) (logs in comments). I will report further RT results as they complete.
