Cranelift: Revive division-by-constant magic sequences (#11129)

Cranelift: Revive division-by-constant magic sequences (#11129)

* Revive the old module for generation division-by-constant magic numbers

* Add proptests for divide-by-constant magic number generators

* Use division-by-constant magic sequences in the ISLE mid-end

The application of these sequences have been ported to ISLE now to better
integrate with our existing mid-end optimizations and to allow for recursive
rule application in the optimized right-hand sides.

Fixes https://github.com/bytecodealliance/wasmtime/issues/6049

* Fix transcription to ISLE and failing tests

* address review feedback

* Fix ci test failure
