Select ARIA violation around not having an accessible name

The [ember-paper Select](https://miguelcobain.github.io/ember-paper/#/components/select) component renders a wrapper element `` that absorbs any attributes, not allowing any `aria-label` or `aria-describedby` or similar accessibility attributes to be passed to the underlying `` that Ember Power Select outputs. This results in a `[serious]: ARIA input fields must have an accessible name` https://dequeuniversity.com/rules/axe/3.5/aria-input-field-name?application=axeAPI.

This is even true if you supply a `@label="my label"`.

Running a `a11yAudit` with popular [`ember-a11y-testing` addon](https://github.com/ember-a11y/ember-a11y-testing) fails with the above rule violation. (For a full reproduction, I awaited for a click on the dropdown to show the options first)

_P.S. I haven't investigated the `aria-valid-attr-value` failure yet, but it may be a semi-related A11y concern_
