New 1d evp solver (CICE-Consortium#895)

* New 1d evp solver

* Small changes incl timer names and inclued private/publice in ice_dyn_core1d

* fixed bug on gnu debug

* moved halo update to evp1d, added deallocation, fixed bug

* fixed deallocation dyn_evp1d

* bugfix deallocate

* Remove gather strintx and strinty

* removed 4 test with evp1d and c/cd grid

* Update of evp1d implementation

- Rename halo_HTE_HTN to global_ext_halo and move into ice_grid.F90
- Generalize global_ext_halo to work with any nghost size (was hardcoded for nghost=1)
- Remove argument from dyn_evp1d_init, change to "use" of global grid variables
- rename pgl_global_ext to save_ghte_ghtn
- Update allocation of G_HTE, G_HTN
- Add dealloc_grid to deallocate G_HTE and G_HTN at end of initialization
- Add calls to dealloc_grid to all CICE_InitMod.F90 subroutines
- Make dimension of evp1d arguments implicit size more consistently
- Clean up indentation and formatting a bit

* Clean up trailing blanks

* resolved name conflicts

* 1d grid var name change
