Currently the Label component accepts only a string for the label content

Adding a template would allow to customise the label contents e.g. by adding an icon.

When the for attribute of the native label is set to the id of the native input (and it's wisely generating guids for those so they're unique) there is no need for the aria-labelledby to point back to the id of the label.

The only time you need that aria-labelledby pointing back to the label is on components that aren't using a native input/select/textbox element, like kendo-dropdownlist.

Remove the aria-labelledby for cases when native HTML elements are associated.
