Add Z3_decl_kind enumeration for finite_set operators

Browse source 
- Added Z3_OP_FINITE_SET_* enumeration values (0xc000 range) to z3_api.h
- Added documentation for all 13 finite_set operators
- Added translation cases in api_ast.cpp for mapping internal finite_set
  enum values to external Z3_decl_kind values
- All operators tested and working correctly
