Make SCCs and graph traversals reusable (#12590)

* Make SCCs and graph traversals reusable

This moves our existing SCC computation and DFS graph traversals out of
`wasmtime::compile` and into `wasmtime_environ::graphs`, where they can be
reused elsewhere in the workspace. These functions and types were already
generally generic over an iterator of nodes and/or an edge function to get a
particular node's successors, but I've gone one step further and packaged up
those two things together into a `Graph` trait.

In the process, I also moved the `NonMaxU32` type to `wasmtime_internal_core`
and made it so we have other non-max integer types as well.

This will let us reuse SCC computation in our GC ops fuzzer, where we need SCCs
to figure out how to merge fuzzer-generated rec groups, if necessary, since
cyclic type references are constrained to within the same rec group. The GC ops
fuzzer can also reuse the DFS traversal code in its topological sorting of
supertypes and subtypes as well.
