refactor delete to remove cobra dependency
FYI. As part of CLI Q1 roadmap, we would like to reduce the dependency of Cobra from actual commands implementations. In this PR, I tried to refactor delete command to achieve this. @kubernetes/sig-cli-misc a quick review is quite welcome, and I am just working on more PRs.

move api/errors to apimachinery
`pkg/api/errors` is a set of helpers around `meta/v1.Status` that help to create and interpret various apiserver errors. Things like `.NewNotFound` and `IsNotFound` pairings. This pull moves it into apimachinery for use by the clients and servers.
@smarterclayton @lavalamp First commit is the move plus minor fitting. Second commit is straight replace and generation.

replace global registry in apimachinery with global registry in k8s.io/kubernetes
We'd like to remove all globals, but our immediate problem is that a shared registry between k8s.io/kubernetes and k8s.io/client-go doesn't work. Since client-go makes a copy, we can actually keep a global registry with other globals in pkg/api for now.

**What this PR does / why we need it**:
ShortcutExpander has been extended in a way that it will examine a hardcoded list of tuples anticipated from the server when searching for an alternative name for the resource.
Note that the list is ordered and the first match will yield the extended resource's name.
One important thing to highlight is that the ShortcutExpander will fall back to PriorityRestMaper to determine the group for the resource.
Also this PR introduces a new shortcut namely sc which will resolve to storageclasses within storage.k8s.io group

Add json,yaml output format support to kubectl create, kubectl apply
Fixes: https://github.com/kubernetes/kubernetes/issues/37390
**Release note**:
```release-note
Added support for printing in all supported `--output` formats to `kubectl create ...` and `kubectl apply ...`
```
This patch adds the ability to specify an output format other than
"name" to `kubectl create ...`. It can be used in conjunction with the
`--dry-run` option. Converts unstructured objects into known types in
order to support all `--output` values.
The patch prints `*resource.Info`s returned by the server. If a resource does not yet exist (and the `--dry-run` option is not set), the resource is created and printed in the specified format.

**What this PR does / why we need it**:
the current description is

but ,

the header has been printing , so the default condition is printing headers.

the header has been not printing

the header has been printing

Reduce decode times by changing the kubectl.Filter(runtime.Object, *PrintOptions)'s return values
**What this PR does / why we need it**:
In kubectl/cmd/get.go, we use the function filterFuncs.Filter() to decode data and filter the object. But in the following function printer.PrintObj() decodes the data again.
I made these modifications to reduce the decoding times by changing the filterFuncs.Filter()'s returned values. We can get the decoded object from this function and pass it to the following printer.PrintObj(), so not to waste time to decode again.

Remove json serialization annotations from internal types
fixes#3933
Internal types should never be serialized, and including json serialization tags on them makes it possible to accidentally do that without realizing it.
fixes in this PR:
* types
* [x] remove json tags from internal types
* [x] fix references from serialized types to internal ObjectMeta
* generation
* [x] remove generated json codecs for internal types (they should never be used)
* kubectl
* [x] fix `apply` to operate on versioned object
* [x] fix sorting by field to operate on versioned object
* [x] fix `--record` to build annotation patch using versioned object
* hpa
* [x] fix unmarshaling to internal CustomMetricTargetList in validation
* thirdpartyresources
* [x] fix encoding API responses using internal ObjectMeta
* tests
* [x] fix tests to use versioned objects when checking encoded content
* [x] fix tests passing internal objects to generic printers
follow ups (will open tracking issues or additional PRs):
- [ ] remove json tags from internal kubeconfig types (`kubectl config set` pathfinding needs to work against external type)
- [ ] HPA should version CustomMetricTargetList serialization in annotations
- [ ] revisit how TPR resthandlers encoding objects
- [ ] audit and add tests for printer use (human-readable printer requires internal versions, generic printers require external versions)
- [ ] add static analysis tests preventing new internal types from adding tags
- [ ] add static analysis tests requiring json tags on external types (and enforcing lower-case first letter)
- [ ] add more tests for `kubectl get` exercising known and unknown types with all output options

Remove "pod xxx deleted" message from kubectl run --rm
This is a follow-on to https://github.com/kubernetes/kubernetes/issues/28695
Its unnecessary to print the message when the user asked for it.
We should only show a msg (error) when we didn't do what they asked.
Also showing this in a "kubectl run" is bad because it then
gets appended to the user's output and they would then have to strip
it off if they want to use the output in some follow-on processing.

* creating a new cloner means we have no generated functions registered
* passing non-addressable values doesn't pick up generated deep copy functions, and forces us into reflective mode

fix local resource output when `-f` not specified
**Release note**:
```release-note
release-note-none
```
`kubectl set image` does not have a `--dry-run` option. Although it offers a
`--local` flag, it does not support server request, limiting input to that of stdin
or that of a local file.
This patch adds a `--dry-run` option to the `kubectl set image` command,
allowing for resources from the server to be selected, without making any
mutations.

add resource prefix to multiple items w/ same kind
**Release note**:
```release-note

```
This patch ensures that a resource prefix is added to multiple items of
the same kind, when using `kubectl get all`. Before, a prefix was added only
when a single item was returned on `kubectl get all`, but ignored if only a
single resource kind existed but multiple items for that kind were
returned.
**Example**
```
$ kubectl get all
No resources found.
$ kubectl create service loadbalancer testsvc1 --tcp=8080
