Embed CRD manifests via go:embed instead of codegen (#10329)

config/crd/{v1,v2alpha1}/crds/crds.go were generated files that
gzip-compressed the CRD YAML bases into committed []byte literals via
hack/crd-gen, requiring `go generate` and a dedicated CI drift check
(hack/verify-generated-crd-code.sh). This made the files large,
unreviewable in diffs, and a frequent source of merge conflicts.

Replace the generated files with config/crd/{v1,v2alpha1}/crds.go
using `//go:embed bases/*.yaml` to embed the already-committed YAML
manifests directly, decoding them the same way at init. Since Go's
go:embed can't reach outside a file's own directory tree, the crds
package now lives alongside bases/ instead of in a bases-sibling
subdirectory; import paths in pkg/install and pkg/controller were
updated accordingly.

Drop hack/crd-gen and hack/verify-generated-crd-code.sh entirely, and
trim their references from update-3generated-crd-code.sh and the
codespell skip-list. No codegen step remains, so no drift is possible.

Fixes #10328
