[KodiProps] Deprecated license_url / license_url_append properties

[CastagnaIT]

Description

Deprecated for future removal of: inputstream.adaptive.license_url inputstream.adaptive.license_url_append

since the PVR interface API bug has been fixed on Kodi 22 Then add-ons/playlists can use the regular properties to set the license url without the needs to split the url string

Motivation and context

fix on board https://github.com/xbmc/xbmc/pull/25552
