P4 to Git Change 1451293 by gandryey@gera-w8 on 2017/08/24 13:37:00

SWDEV-129129 - [[CQE OCL][Vega vs Fiji] Upto 12% Performance drop observed on VEGA10 compared to FIJI while running BlackMagic Davinci Resolve
	The app creates/destroys hundred resources each frame. PAL path was removing the destroyed resources from the resident list, although the resource was kept in the cache. This change does the follwoing:
	- Switch TS tracking from a map in VirtualGPU to resource
	- Don't remove references until the actual memory destruction
	- Add a residency threshold to avoid OS resident/eviction calls
