Epic: Multiplatform build of vcell-solvers on GitHub CI

[jcschaff]

base solvers

• FV solver (non-PETSc)
• Smoldyn
• nonspatial Stochastic
• NFSim
• Moving Boundary Solver

Hy3S solvers (needs Fortran reconciled with LLVM toolchain)

• Hybrid_EM
• Hybrid_MIL
• Hybrid_MIL_Adaptive

Chombo solvers (difficult multi-step build)

• Chombo2D (without parallel)
• Chombo3D (without parallel)
