Rollup merge of #141513 - nia-e:allocbytes-extend, r=RalfJung

interpret: add allocation parameters to `AllocBytes`

Necessary for a better implementation of [rust-lang/miri#4343](https://github.com/rust-lang/miri/pull/4343). Also included here is the code from that PR, adapted to this new interface for the sake of example and so that CI can run on them; the Miri changes can be reverted and merged separately, though.
