Add TypeEntry, base class for type section entries (#1349)

The type section currently only has one form: functions. With the GC
proposal, at least two more forms are added: struct and array. To
facilitate this:

* Rename FuncTypeModuleField -> TypeModuleField
* Rename Module::func_types -> Module::types
* Rename func_type_bindings -> type_bindings
* TypeEntry is added as a base class of FuncType
* TypeModuleField stores a unique_ptr to a TypeEntry
