[idd] driver: relocate the HW cursor thread into CSwapChainProcessor

Browse Source 
It is invalid to call `IddCxMonitorSetupHardwareCursor` before
`IddCxSwapChainSetDevice`. This fixes this by moving the thread into
CSwapChainProcessor and starting it after `IddCxSwapChainSetDevice`
has succeeded.
