Codegen refactoring to simplify split layout changes.

Use `$this_field$` and `$from_field$` in more places.
Except in Serialize functions, we must keep using `this_.$field_$` there because we interleave split and non-split fields to keep field order stable in the wire.

Collapse the split-vs-!split codegen for repeated fields by making RawPtr forward some operations.
