Add +k8s:maxBytes and +k8s:minBytes OpenAPI representation

[BasavarajBankolli]

What this PR does

Adds support for the +k8s:maxBytes and +k8s:minBytes validation markers in kube-openapi.

These markers are mapped to OpenAPI maxLength and minLength respectively, allowing byte-based validation constraints to be expressed in API definitions.

Implementation

• Added MaxBytes and MinBytes fields to commentTags
• Added validation for negative values and range conflicts
• Prevented simultaneous use of maxLength with maxBytes and minLength with minBytes
• Mapped byte markers to length constraints during schema generation

Fixes: kubernetes/kubernetes#137613
