Proper subdevice count being returned now in GfxCoreHelper
path, as previous method ignored the usage of the
ReturnSubDevicesAsApiDevices flag.

Added getDefaultDeviceHierarchy call that describes default device
hierarchy for a gfx core. Refactored L0 and OCL paths to use this
value by default and override this value when user sets
ZE_FLAT_DEVICE_HIERARCHY environment variable or
ReturnSubDevicesAsApiDevices debug key.
Updated ReturnSubDevicesAsApiDevices to force COMPOSITE device hierarchy
when set to 0.

MaxDualSubSlicesSupported is filled inside GT_SYSTEM_INFO
structure when querying the KMD appropriately with the
number of enabled DualSubSlices. However we need to find
the highest index of the last enabled DualSubSlice.
For proper allocation of thread scratch space, allocation
has to be done based on native die config (including unfused
or non-enabled DualSubSlices). Since HW doesn't provide us a
way to know the exact native die config, in SW we need to
allocate RT stacks with enough size based on the last used
DualSubSlice.
The IsDynamicallyPopulated field in GT_SYSTEM_INFO is used to
indicate if system details are populated either via Fuse reg.
or hard-coded. Based on this field's value, we calcuate the
numRtStacks appropriately.
