Vuetify: [Feature Request] Set v-autocomplete browser-autocomplete default value to "disabled", instead of "off"

[ben1lam8]

Problem to solve

Chrome intentionally ignores "off" and "false" values for an input autocomplete attribute, to fit the WHATWG autofill standard (well... 'fit' their way).

• https://bugs.chromium.org/p/chromium/issues/detail?id=468153#c164
• https://developers.google.com/web/updates/2015/06/checkout-faster-with-autofill

Hence, v-autocomplete still prompts "autofilled browser suggestions" where their browser-autocomplete default value is "off".

Proposed solution

Set the browser-autocomplete default value to something that doesn't match any WHATWG autofill standard, nor Chrome exception. Such as "disabled".

To keep the browser autofill behaviour, we would have to clearly define the prop to 'on' or to a WHATWG autofill token value.

In v2 the default autocomplete value has been removed.

I should probably make this a separate issue but with v2, the Chromium autofill sometimes shows suggestions for the v-text-field, v-autocomplete and v-combobox. The browser autofill suggestions overlay the suggestions provided by v-autocomplete and v-combobox. Those two components should disable browser autofill functionality. It would be good if it was disabled by default with an option to enable it for v-text-field though.
