Remove incomplete uint64 support from JSON unmarshaling

**What this PR does / why we need it**:
Removes `uint64` support from JSON unmarshaling because:
- [unsigned types should not be used](https://github.com/kubernetes/community/blob/master/contributors/devel/api-conventions.md#primitive-types);
- big numbers (53+ bits) cannot be properly round tripped via JSON in most languages.

**Which issue(s) this PR fixes**
Fixes #62769.

**Special notes for your reviewer**:
This is an alternative approach to https://github.com/kubernetes/kubernetes/pull/62775.
