media: uapi: h264: Clarify pic_order_cnt_bit_size field

Browse source 
Since pic_order_cnt_bit_size is not a syntax element itself, explicitly
state that it is the total size in bits of the pic_order_cnt_lsb,
delta_pic_order_cnt_bottom, delta_pic_order_cnt[0], and
delta_pic_order_cnt[1] syntax elements contained in the slice.
