Implement support for renaming fields in Darwin codegen. (#24154)

* Implement support for renaming fields in Darwin codegen. This adds support for renaming struct, event, and command fields. Also fixes a bug that was introduced where the getter for newPosition was mis-named. * Add support for renaming structs and events too. * Add support for renaming enums and bitmaps as well. * Add support for renaming enum and bitmap values as well.
