add seat sub command 'xcursor_theme'
New 'seat <name> xcursor_theme <theme> [<size>]' command that configures the default xcursor theme. The default seat's xcursor theme is also propagated to XWayland, and exported through the XCURSOR_THEME and XCURSOR_SIZE environment variables. This is done every time the default seat's configuration is changed.
