Rollup merge of #111315 - Swatinem:rm-identitiy-future, r=Mark-Simulacrum
Remove `identity_future` from stdlib This function/lang_item was introduced in #104321 as a temporary workaround of future lowering. The usage and need for it went away in #104833. After a bootstrap update, the function itself can be removed from `std`.
