Rollup merge of #62245 - RalfJung:miri-extra-fn, r=eddyb,zackmdavis
Miri engine: support extra function (pointer) values We want to add basic support for `dlsym` in Miri (needed to run the latest version of `getrandom`). For that to work, `dlsym` needs to return *something* that can be stored in a function pointer and later called. So we add a new `ExtraFnVal` type to the `Machine` trait, and enable Miri's memory to associate allocation IDs with such values, so that `create_fn_alloc` and `get_fn` can work on *both* `Instance` (this is used for "normal" function pointers) and `ExtraFnVal`.
