[naga] Leave Module as the last thing in naga/src/lib.rs.

Move the definitions of `RayFlag` and `RayQueryIntersection` above the
definition of `Module`, so that `Module` remains the last definition
in `lib.rs`. This is helpful for navigation.

This commit is purely code motion, and makes no changes to
functionality.
