chore: remove aya_obj -> obj alias

When `aya::obj` was migrated to be its own crate `aya-obj`, the `obj`
alias was created to preserve existing imports that relied on
`crate::obj`.

This resulted in 3 ways to import `aya-obj` objects:
- `use aya_obj::*`
- `use obj::*`
- `use crate::obj::*`

The `obj` alias is now removed to avoid confusion, and all `obj` imports
are funneled through `aya_obj`.
