sdm: color-manager: Detect first frame of UI to apply color-mode.

Default color-mode is applied on the first frame of UI screen.
sdm.boot_anim_layer_count property is used to configure the
number of layers in boot animation process. Any commit with
more layers than sdm.boot_anim_layer_count is treated as first frame
of UI and default color-mode is applied at this point.
