interpret: support for per-byte provenance

Also factors the provenance map into its own module.

The third commit does the same for the init mask. I can move it in a separate PR if you prefer.

Fixes https://github.com/rust-lang/miri/issues/2181

2414a4c31a Rollup merge of #103625 - WaffleLapkin:no_tyctxt_dogs_allowed, r=compiler-errors 
Accept `TyCtxt` instead of `TyCtxtAt` in `Ty::is_*` functions

Functions in answer:

- `Ty::is_freeze`
- `Ty::is_sized`
- `Ty::is_unpin`
- `Ty::is_copy_modulo_regions`

This allows to remove a lot of useless `.at(DUMMY_SP)`, making the code a bit nicer :3

d49e7e7fa1 Auto merge of #103279 - compiler-errors:normalize-hack-back, r=lcnr 
Add eval hack in `super_relate_consts` back

Partially reverts 01adb7e98d.

This extra eval call *still* needs to happen, for example, in `normalize_param_env_or_error` when a param-env predicate has an unnormalized constant, since the param-env candidates never get normalized during candidate assembly (everywhere else we can assume that they are normalized fully).

r? `@lcnr,` though I feel like I've assigned quite a few PRs to you in the last few days, so feel free to reassign to someone else familiar with this code if you're busy!

cc #103243 (fixes the issue, but don't want to auto-close that until a backport is performed).

801e32647e Rollup merge of #103315 - RalfJung:interpret-switchint-ice, r=bjorn3 
interpret: remove an incorrect assertion

This fixes an ICE in Miri, [reported](https://rust-lang.zulipchat.com/#narrow/stream/269128-miri/topic/SwitchInt.20with.20no.20targets.3F) by `@saethlin.` The faulty assertion was introduced by 432535da2b, when a previously correct assertion checking that the `otherwise` target exists got replaced by this assertion checking that at least one more target beyond `otherwise` exists.

Sadly we don't have a small reproducer so I don't think we can easily add a testcase.

8c0f8a285f Rollup merge of #101985 - RalfJung:generate_stacktrace, r=oli-obk 
interpret: expose generate_stacktrace without full InterpCx

In Miri we sometimes want to emit diagnostics without having a full `&InterpCx` available. To avoid duplicating code, this adds a way to get a stacktrace from an arbitrary slice of interpreter frames, that Miri can use with access to just a thread manager.
