Evas (wayland_egl): More bug fixes & cleanups ! :)

When we create the egl window we should take rotation into
consideration, so account for that. Add an 'edges' variable to the
engine info structure. This is needed so we can implement resizing
windows from the top also. Make sure to use
wl_egl_window_get_attached_size and determine the edge we are resizing
from, so we can calculate the difference in sizes to send to
wl_egl_window_resize.

Add __UNUSED__ to function paramaters where it was missing, and fix
some compiler warnings.
