xwm: move FILE to the callers of dump_property()

Browse source 
This is preparation for using the weston-debug infrastructure for
WM_DEBUG. dump_property() may be called from different debugging
contexts and often needs to be prefixed with more information.

An alternative to this patch would be to pass in the weston_debug_scope
as an argument to dump_property(), but then all callers would need to be
converted to weston-debug infra in a single commit.

Therefore require the callers to provide the FILE* to print to.
