Description
Typescript should allow the parser function to return null or undefined. Sometimes, we want to leave a number field empty and not default to 0.
See the example below:
https://codesandbox.io/s/inputnumber-antd-14150-forked-higgh?file=/index.tsx
Sidenote: <InputNumber<number | undefined> does not work because T extends valueTypes which is number | string

Start with the InputNumber type declarations and the parser function described in the issue, then reproduce the behavior in the linked CodeSandbox at index.tsx. Done means TypeScript accepts parser results of null or undefined for an empty number field without defaulting the value to 0.
