Extend meta object from useForm with meta state per field

[NvdB31]

Is your feature request related to a problem? Please describe.

When building a form, it's a good UX practice to show the validation state of a field as indeterminate until the user has finished typing. Currently, this is not possible when using useForm, because the meta object only contains the dirty and touched states for the entire form.

This is also inconsistent with useForms objects values and errors, which are objects with keys of each field.

Describe the solution you'd like

I propose to be able to do the following:

const { meta } = useForm({
  firstName: string().required(),
  lastName: string().required()
})

Which would give me the state for the form as a whole plus the meta for each field included:

const meta = {
    dirty: true,
    pending: false,
    touched: true,
    valid: false,
    // keys with the meta for each field
    firstName: {
      dirty: true,
      pending: false,
      touched: true,
      valid: true,
    },
    lastName: {
      dirty: false,
      pending: false,
      touched: false,
      valid: false,
    },
  };

This solution would allow me to pass specific meta details to each field's component, without having to rely on useField, making the code more compact.
