Subject: [PATCH] Adjust to upcoming Julia 1.12 change in implicit world age
 increment

In 1.12, we'll be cleaning up and making consistent when world age
increment happens. This package is currently relying on implicit world
age increments that may go away in 1.12. See https://github.com/JuliaLang/julia/pull/56509.
This PR adds appropriate annotations that the world age increment
is required because the `_generate_*` invocations in the macro read
the result of the previous eval. This PR strictly retains existing
behavior. A potentially better solution may be to `invokelatest`
the `_generate_*` functions, which would also allow this code
to work at non-toplevel (which may nor may not be desirable).
