Fix issue of using the wrong id when finding pixmap client
Previously, we were passing in the wl window id into the
pixmap_find_client function. This is improper as the e_pixmap_new
functions take the surface resource id. To solve this, we will get the
Ecore_Wl2_window from the Evas_Object, fetch the surface id from that,
then pass those into e_pixmap_find_client.
This resolves an issue where the everything module was not working
