x11: sanitize window title to UTF-8 for EWMH

Both _NET_WM_NAME and _NET_WM_ICON_NAME (part of Extended Window Manager
Hints) require that the string is UTF-8*. mpv was not doing this and
thus violating the spec. Just sanitize the title for these two atoms.
Note that XA_WM_NAME and XA_WM_ICON_NAME have no such requirement so
those atoms are left the same. Fixes #8812.
