gtk4 a11y: Map states to corresponding gtk a11y properties
For those states in
`com::sun::star::accessibility::AccessibleStateType::EDITABLE`
that have a corresponding `GTK_ACCESSIBLE_PROPERTY_*`, set
that property when creating a new `LoAccessible`.
This e.g. makes Accerciser show the "multiline" and "multi selectable"
AT-SPI states for a Writer paragraph when using the gtk4 VCL plugin.
State updates are not handled yet, since a11y event handling is
currently not implemented in the gtk4 VCL plugin yet.
