What type of PR is this?
/kind api-change
/kind bug

What this PR does / why we need it:

Explores fixing #3030 by:

  • generating code in conversion to populate apiVersion/kind in external types
  • avoiding clearing apiVersion/kind when decoding into external types

This is very WIP/experimental. Still need to:

  • discuss this approach to populating apiVersion/kind
  • measure allocation impact to list conversions (cc @kubernetes/sig-scalability-pr-reviews)

If we move forward with this approach, still need to:

  • clean up the GVK-clearing decoder
  • figure out a better way to avoid short-circuit memory-equivalent unsafe copy of list items
  • add tests around proto decoding preserving GVK in lists and individual items

Which issue(s) this PR fixes:
Fixes #3030
Fixes #80609

Does this PR introduce a user-facing change?:

`apiVersion` and `kind` fields are now correctly populated in individual list items

Additional documentation e.g., KEPs (Kubernetes Enhancement Proposals), usage docs, etc.:
