[dev.regabi] cmd/compile: remove {Ptr,Set}Init from Node interface
This CL separates out PtrInit and SetInit into a new InitNode extension interface, and adds a new TakeInit helper function for taking and clearing the Init list (if any) from a Node. This allows removing miniNode.SetInit and miniNode.PtrInit, which in turn allow getting rid of immutableEmptyNodes, and will allow simplification of the Nodes API. It would be nice to get rid of the default Init method too, but there's way more code that expects to be able to call that at the moment, so that'll have to wait. Passes toolstash -cmp.
