Move intrinsics lowering pass from the optimization phase (where it would not run if -Zmir-opt-level=0), to the drop lowering phase where it runs unconditionally. The implementation of those intrinsics in code generation and interpreter is unnecessary. Remove it.

@Dylan-DPC the current version should account for rollup CI failure. |

cc @RalfJung and @oli-obk (part of @rust-lang/miri which I can't ping) per this comment. They might have objections and/or may need to adjust Miri accordingly. |

This LGTM, and thanks for the heads-up! I'll update Miri once this lands. When more intrinsics are added to the lowering pass, please let me know. |

remove intrinsic that is now implemented in the rustc side Since rust-lang/rust#80040, we can rely on the pass introduced in rust-lang/rust#79049 to lower away `forget`.
