feat(form-core): add canSubmitWhenInvalid form option

[matthiasschwarz]

Allows to submit a form when invalid with the new canSubmitWhenInvalid form option.

Resolves #1109.

Out of curiosity, is there a reason for the two tests? onMount and onChange?

This logic dose not work, if you run pnpm test:lib you will get failing tests.

would something like this work?

const submitInvalid = this.options.canSubmitWhenInvalid ?? false
const canSubmit =
  (currBaseStore.submissionAttempts === 0 &&
    !isTouched &&
    (!hasOnMountError || submitInvalid)) ||
  (!isValidating &&
    !currBaseStore.isSubmitting &&
    (isValid || submitInvalid))
