rust/detect: Create detect module for rule parsing

This commit creates a module named "detect" for rule parsing logic. As
part of this commit, detect.rs is moved from its toplevel position into
the new module. Thus, use crate::detect::detect to refer to items within
detect.rs (instead of create::detect).

Ticket: 5077
