Mixed precision amip_interp_mod (#1365)

BREAKING CHANGE: Several variables and arrays which were previously public have been made private.
These variables and arrays are not used in ice_amip or ocean_amip.
amip_interp_type(r4_kind) and amip_interp_type(r8_kind) should be used for
r4_kind and r8_kind precision, respectively. amip_interp_type without a kind
parameter defaults to r8_kind.
