add a "max-disparity" property

The disparity element based on OpenCV is used for calculating disparities
between two input images, but the current element only supports inputs whose
maximum disparity is smaller than 16/32/64. (This fixed value depends on the
algorithm type)

For supporting high-resolution images with larger disparity, I added a new
property, "max-disparity". It can control a disparity size the element handles.

You can check it using the following command.

gst-launch-1.0 multifilesrc location=../L0000000000.png ! pngdec ! videoconvert
! video/x-raw,colorimetry="1:1:0:0" ! disp0.sink_right multifilesrc
location=../R0000000000.png ! pngdec ! videoconvert !
video/x-raw,colorimetry="1:1:0:0" ! disp0.sink_left disparity max-disparity=64
name=disp0 method=sbm disp0.src ! videoconvert ! xvimagesink sync=false
