### What? In #83074 we changed how turbo task objects were registered to use the `inventory` crate. This PR adds a new `inventory_submit!` macro that wraps the existing `inventory::submit` function with a `#[cfg(not(rust_analyzer))]` attribute to prevent Rust Analyzer choking on the generated code. See example error  Because the inventory code does not affect any API surfaces this is safe and if anything should improve rust-analyzer performance
