gtk4 a11y: Set accessible name and description

Set the accessible name and accessible description
via the corresponding properties in the gtk4 a11y API,
`GTK_ACCESSIBLE_PROPERTY_LABEL` (accessible name) and
`GTK_ACCESSIBLE_PROPERTY_DESCRIPTION` (accessible description).

Drop the initial proof of concept that was setting the
text returned by the Text interface as accessible name instead.

This also makes it much easier to find a specific item in
the LO a11y tree in Accerciser.
