migrate to record (#1665)

* migrate to record

* chore: update project files and clean up unused references

* refactor: convert classes to records and simplify constructors for IntOrString, ResourceQuantity, and V1Patch

* fix: define IsExternalInit to resolve CS0518 error in IntOrString

* refactor: change IntOrString and ResourceQuantity from records to structs, update implicit conversions, and simplify null checks

* refactor: add JsonPropertyName attribute to Value property in IntOrString struct

* refactor: simplify V1Patch constructor and improve argument validation

* refactor: remove unnecessary CultureInfo parameter in ToInt method

* Update src/KubernetesClient/Models/ResourceQuantity.cs
