Mojo Bindings: Support handles in native structs

Changes [Native] struct serialization to use an IPC::Message instead of
a base::Pickle, allowing ParamTraits for [Native]-mapped types to be
parameterized over IPC::Message once again. In order to support this,
IPC::Message and related attachment support code has been moved into a
separate leaf target in //ipc, avoiding circular dependencies with Mojo
bindings.

Also changes the wire representation of native structs to allow for
typed Mojo handle attachments, and wires up native struct
serialization to automatically convert between IPC::MessageAttachments
and these typed mojom handles.

The net result here is that [Native] mojom structs can be mapped to
native types whose ParamTraits use message attachments.
