Weston: add the dynamic mode setting through json IPC [1/1]

PD#SWPL-4864

Problem:
New tools display_framework provide a ipc framework for userspace display.
we use the private sysfs to set displaymode, Now we need use the standard
drm ioctl.so use ipc framework to tell weston to switch display mode

Solution:
ioctl only can be accessed by weston, so add IPC framework to
set mode through weston.
