feat: Slice.posGE and Slice.posGT (#12301) 
This PR introduces the functions `(String|Slice).posGE` and
`(String|Slice).posGT` will full verification and deprecates
`Slice.findNextPos` in favor of `Slice.posGT`.

The KMP implementation is adapted to use these two new functions.

Various useful string and order lemmas are added along the way.

Also add a `simp` attribute to `Std.le_refl` and fix the resulting
fallout (yes, this would have been better as a separate PR).
