Validate token length of TokenReview
**What this PR does / why we need it**:
I find API Resource TokenReview has no validation yet. Without validation, client may post unexpected data to API Server. I think we need to validate it before processing it.
This PR Validate TokenReview Resource.
Fixes#50588
**Special notes for your reviewer**:
**Release note**:
```release-note
NONE
```
Add support for creating resources that are not immediately visible to
naive clients, but must first be initialized by one or more privileged
cluster agents. These controllers can mark the object as initialized,
allowing others to see them.
Permission to override initialization defaults or modify an initializing
object is limited per resource to a virtual subresource "RESOURCE/initialize"
via RBAC.
Initialization is currently alpha.
