Generates a hint tag for the given model attribute.
The hint text is the hint associated with the attribute, obtained via [[Model::getAttributeHint()]].
If no hint content can be obtained, method will return an empty string.
@param Model  $model the model object
@param string $attribute the attribute name or expression. See [[getAttributeName()]] for the format
about attribute expression.
@param array  $options the tag options in terms of name-value pairs. These will be rendered as
the attributes of the resulting tag. The values will be HTML-encoded using [[encode()]].
If a value is null, the corresponding attribute will not be rendered.
The following options are specially handled:

- hint: this specifies the hint to be displayed. Note that this will NOT be [[encode()|encoded]].
If this is not set, [[Model::getAttributeHint()]] will be called to get the hint for display
(without encoding).
@param string   $encoding

See [[renderTagAttributes()]] for details on how attributes are being rendered.

@return string the generated hint tag
