refactor: move no_cycles_test.go to gno.land/pkg/gnoland

[moul]

examples/no_cycles_test.go was introduced in #3304, and we still want to keep it.
However, it creates an issue because the examples folder contains code that is not an example, which is not user-friendly.
Additionally, I believe it is currently not tested by the CI.

I suggest moving it to gno.land/pkg/gnoland, as I think that would be a suitable location, but I am open to other suggestions.

Depending on #4351, we may need to patch this test file to ignore stdlib.

The move looks good, but the test doesn't work. Maybe @n0izn0iz could make a PR fixing it up as well?

@thehowl @moul I updated the test in this branch #4439
Couldn't open a PR against moul's fork so had to open it against gnolang's

[thehowl]

merged #4439 instead
