And update a few callers as examples of motivation. (there are a
couple others, but these are the ones where it's prettier)

The standard library includes these for strings and byte slices,
but it lacks similar functions for generic slices of comparable types.
Although they are not as commonly used, these functions are useful
in scenarios such as working with field index sequences (i.e., []int)
via reflection.

We had this in a different repo, but moving it here, as this a more

I think we have it a few other places too.
And use slices.Equal in wgengine/router too. (found while looking for callers)

Now that we're using rand.Shuffle in a few locations, create a generic
shuffle function and use it instead. While we're at it, move the
interleaveSlices function to the same package for use.
