hwc: Enable downscale feature through system property
Add support to turn the MDP downscale feature ON through the
use of a system property. 'sys.hwc.mdp_downscale_enabled' shall be
set to 'true' in build.prop file to enable this functionality.
This is required for OEMs that might have privacy concerns over panel
size information being exposed.

libvirtual: Cleanup patch for DRC feature
Separated the logic for setting virtual display attributes into 3
functions that:
1. Initialize the virtual res. on an ONLINE event
2. Set virtual res. to match primary res (MDP downscale path)
3. Set MDP downscale mode for either DRC or MDP downscale path

hal: adding support for DRC on WiFi display
When Dynamic Resolution Change (DRC) is triggered in the WiFi display
stack, it results in a PAUSE and a RESUME event. During DRC, the
dimensions of the framebuffer are changed. To support DRC we need to:
1. Check if a RESUME event is the result of a valid DRC event
2. Reconfigure the display's attributes to reflect resolution change
3. Enable MDP downscaling when necessary (Valid DRC cases)

hwc: Perform MDP downscaling for WFD/HDMI Scenario
On WFD/HDMI connection, if the configured resolution is less than
Primary Resolution, Display HAL does the following:
1. sends hpd notification to SF with primary resolution.
2. configures MDP pipes with configured Resolution.
This is done to improve UI quality as MDP has better downscale
filter options compared to GPU.
