Combined PR: hpc-stack locations, Disable Fused Multiply Add, and Ena…

…ble usage of shared pio (ufs-community#1645)

* Gaea system: change in hpc-stack location, miniconda3 (EPIC-managed)

* move DISABLE_FMA to one if at the end

* only disable fma on wcoss if FASTER=ON

* Update CMakeModules to develop; remove STATIC requirement from PIO find.
