Comments: Remove `novalidate` attribute from comments form by default.

Browser support for client-side validation is now reliable. Blocking the form submission when there is a missing/invalid field prevents the possibility of losing comment content when bfcache does not restore the previous page when going back.

To retain the `novalidate` attribute, the `comment_form()`'s args now accepts a `novalidate` key which will add the attribute when it is `true`. This can also be supplied by the `comment_form_default_fields` filter, for example:

{{{#!php
add_filter( 'comment_form_defaults', function ( $args ) {
    $args['novalidate'] = true;
    return $args;
} );
}}}

Fixes #47595.
