de84be21 - [WebAssembly][GlobalISel] `G_ADD` (and in-reg ext/trunc related) legalization & selection (#183694)

[WebAssembly][GlobalISel] `G_ADD` (and in-reg ext/trunc related) legalization & selection (#183694) This PR enables `G_ADD` and immediate dependencies (relavent ext and trunc related ops) to be fully legalized and selected. The most important change made is getting the boilerplate for RegBankSelect working. Split from #157161.
