Previously, only a single embedded Kubernetes API version could be specified, resulting in a lack of support for certain GVKs. To address this, the goal is to create and utilize a unified scheme that consolidates Kubernetes API definitions. As a preliminary step, the current method of loading API definitions will be improved.

What this PR does
go:embedand loads the built-in schema from it at runtime.go-bindataandkindfrom the built-in schema generation workflow.This is the artifact-compiler migration only. The generated bundle still represents Kubernetes v1.21.2; combining API definitions from multiple Kubernetes releases will be handled separately.
Why
The existing generated Go assets embed and decode a single Kubernetes OpenAPI protobuf at runtime. Moving that conversion to a deterministic build-time compiler creates a versioned artifact boundary for a future union of Kubernetes API definitions while avoiding additional runtime data and dependencies.
In a local comparison, the resulting kustomize binary was 201,408 bytes smaller (17,396,722 bytes to 17,195,314 bytes).
