feat: enhanced in-place update module to support vertical scaling

[LavenderQAQ]

Ⅰ. Describe what this PR does

Enhanced the in-place update module to enable kruise's workload to modify resources without restarting the pod.

Ⅱ. Does this pull request fix one issue?

Fixes #1212

Ⅲ. Describe how to verify it

Need to kubernetes v1.27 version, and open feature gate InPlacePodVerticalScaling. Here is my kind configuration:

kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
featureGates:
  "InPlacePodVerticalScaling": true
nodes:
- role: control-plane
  image: kindest/node:v1.27.3@sha256:3966ac761ae0136263ffdb6cfd4db23ef8a83cba8a463690e98317add2c9ba72
- role: worker
  image: kindest/node:v1.27.3@sha256:3966ac761ae0136263ffdb6cfd4db23ef8a83cba8a463690e98317add2c9ba72
- role: worker
  image: kindest/node:v1.27.3@sha256:3966ac761ae0136263ffdb6cfd4db23ef8a83cba8a463690e98317add2c9ba72
- role: worker
  image: kindest/node:v1.27.3@sha256:3966ac761ae0136263ffdb6cfd4db23ef8a83cba8a463690e98317add2c9ba72

Build a cloneset (or other workload that includes in-place updates) and set updateStrategy to InPlaceIfPossible. Here's an example:

apiVersion: apps.kruise.io/v1alpha1
kind: CloneSet
metadata:
  name: nginx-cloneset
spec:
  updateStrategy:
    type: InPlaceIfPossible
  replicas: 3
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx-1
        image: nginx:1.21.1
        ports:
        - containerPort: 80
        resources:
          limits:
            cpu: "1"
            memory: "256Mi"
          requests:
            cpu: "0.5"
            memory: "128Mi"

Change the workload's resources, wait a while, and you'll find that the pod's resources will change, and the pod won't restart.

Ⅳ. Special notes for reviews

The control of Status for vertical scaling requires a higher version of the k8s api, which makes this pr need to wait for kruise version upgrade. It cannot be merged at this time because it is not yet complete.

The complete logic needs to wait until the k8s api of kruise is upgraded.
