bindings: Add idl_types.IdlRecordType.

Part 2 of adding support for record<K,V> WebIDL types to the bindings
generator.

This CL lands the uncontroversial bits that the idl_* side (as opposed to
the v8_* side) of the scripts will need:
- A new IdlRecordType type that wraps a record<K,V> and holds information
  about its key and value types.
- Code to parse Record nodes and convert them into IdlRecordTypes when
  parsing IDL files.

In practice, this is still a no-op, as we do not do anything with this new
IDL type just yet.
