e_mod_rotation: send early angle change evt at eval_fetch

e_mod_rotation: send early angle change evt at eval_fetch

the early angle change event is made only for landscape(90|270) client if it
dismatch with rot.curr.
rotation available/preferre request come serveral in sequence, than
apply last req.

with this commit(by calculating in eval_fetch time whether the early
 angle_change event is needed or not) the event flow is going to be changed like below.

condition: curr angle is 0
from
   S <- C   tizen_rotation@37.set_available_angles(2)
   S -> C   tizen_rotation@37.angle_change(2, 243) ====> Angle change 90
   S <- C   tizen_rotation@37.set_available_angles(10)
   S <- C   tizen_rotation@37.set_available_angles(11)
   S <- C   tizen_rotation@37.set_available_angles(15)
   S <- C   tizen_rotation@37.ack_angle_change(243)
   S -> C   tizen_rotation@37.angle_change(1, 245) ===> Angle change 0
   S <- C   tizen_rotation@37.ack_angle_change(245)

to
   S <- C   tizen_rotation@37.set_available_angles(2)
