evas render - drop eo overhead by using ptrs we already have

evas render - drop eo overhead by using ptrs we already have

several calls, specifically evas_object_change_reset,
evas_object_cur_prev, and evas_object_clip_changes_clean that are
called directly or indirectly as part of evas render on at least every
active object if not more, were doing full eo obj lookups when their
calling functions already all had the eo protected data looked up.
tha's silly and just adds overhead we don't need. my test dropped
_eo_obj_pointer_get overhead in perf profiles from 4.48% to 2.65%. see:

vs now the improved:

of course other things "increase their percentage" as oe overhead now
dropped, and things seem to move around a bit, but it does make sense
to do this with no downsides i can see as we already are accessing the
protected data ptr in the parent func.
