Field allocation for SSI capability

[aoloso]

Allocate gridded fields to use the pinflag option needed for the Single System Image (SSI) capability.

Description

In subroutine MAPL_FieldAllocCommit, gridded fields are allocated from scratch with the pinflag option such that the SSI capability of ESMF can be used as necessary. Using thsi capability is essential for the mixed hybrid code with the dyncore hybrid MPI/OpenMP and the rest of GEOS GCM using only MPI.

I think this is meant to go to develop. I'll update the base.

NOTE: I think the CI issues are due to CI quirks grabbing the other feature/aoloso/hybrid_112923 branches in FV and GCM (via mepo checkout-if-exists). I can confirm both Intel Release and Debug run. I'm doing GNU Release and Debug tests now.
