rust: use AppProto from generated bindings instead of duplicating

Have bindgen generate bindings for app-layer-protos.h, then use the
generated definitions of AppProto/AppProtoEnum instead if defining
them ourselves.

This header was chosen as its used by Rust, and its a simple header
with no circular dependencies.

Ticket: #7341
