Support for resource quota on extended resources

**Which issue(s) this PR fixes** :
Fixes #46639 #57300 for  resource quota support

**Special notes for your reviewer**:
One thing to be determined is if it necessary to Explicitly prohibit defining limits for extended resources in quota, like we did for [hugepages](https://github.com/kubernetes/kubernetes/pull/54292#pullrequestreview-74982771), as the resource is not allowed to overcommit.

**Release note**:

```release-note
Support for resource quota on extended resources
```
