Add isValidating by field

Is your feature request related to a problem? Please describe. I implement a spinner when the field is validating. I use isValidating from formState and this will trigger loading for every fields.

Describe the solution you’d like We need isValidating from fieldState the same as isDirty, it could be trigger by field, and we should have isValidatingFields in case of we don’t use Controller.

Describe alternatives you’ve considered At the moment, I have to use trigger and implement isValidatingFields using React State. When I manually trigger the validation, I will setState the field.

Additional context This is my UI screenshot when doing this feature.

This is a feature that I definitely would like to see in RHF soon. 👍🏽

I would also love this feature. In my case, I use a yup schema with the yup resolver and an async api call to validate the field (specifically we check if the handle is available or not). I want to explicitly set a message below the field only when that field is validating, not when the rest of the form is validating, and since yup handles the validation it’s pretty tricky to add this as a local state.
