Move 2D arrays in comsrf to physics/ice or ocean

Ideal engineering time: 1.5 weeks
Move the following 2D arrays from comsrf into physics only modules.

• landm
• sgh
• sgh30
• fv
• ram1
• fsns*
• landfrac_field* (used in restart_physics)
• fsnt
• flns
• srfrpdel
• psm1
• prcsnw
• trefmxav
• trefmnav
  fsns, and landfrac_field will stay as a copy in comsrf, until later (csim uses it). Other arrays are completely removed from comsrf into respective physics modules.
  landfrac_field, can become a local array in restart_physics.
  Work with:
• comsrf.F90 (above arrays)
• physics routines that use them
  camice data:
  Remove use of comsrf:landfrac_field in csim and create local variable within camice to take care of it (leave the comsrf, landfrac_field array in comsrf, just don't use it in camice).
  For later - create local copy of fsns for use within camice (leave comsrf version in for now).
  somoce data:
• Move tsocn from comsrf to somocn.F90 (remove from comsrf)
