libhwc2.1: Support the property control for DPP downscale
Before we can safely enable 1/4 DPP downscale, it is necessary to have a
dynamic control to switch between 1/2 and 1/4 downscale limitation for
DPP. If not specify, the downscale limitation will follow the DPP
configurations in the device tree.
Bug: 170821166
Test: Configure DPP downscale to 0, 1, 2 and check in HWC dump.
