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.

- When communicating with the Metrics Libraries, if one is using a
specific sub device, then the correct physical sub device index and
number of sub devices must be used.
- When Affinity Mask is set, this hierarchy information is lost,
therefore the sub device hierarchy data is stored in a map to each
"device" to be returned to the user allowing for the correct sub device
information to be passed to the metrics library.

- Added Support for users to set ZE_FLAT_DEVICE_HIERARCHY to either FLAT
or COMPOSITE to change how devices are returned in zeDeviceGet and
clGetDeviceIDs.
- COMPOSITE is default behavior that exists today.
- FLAT returns all sub devices which have no sub devices and all root
devices that have no sub devices in zeDeviceGet ie with all devices
flattened out in order.
- Added zeDeviceGetRootDevice for one to retrieve the Root Device for
any SubDevice.

- by default ZE_ENABLE_PCI_ID_DEVICE_ORDER is disabled
- by default devices are sorted by type (discrete first), then by pci order
- when ZE_ENABLE_PCI_ID_DEVICE_ORDER is enabled, devices are sorted by pci id

This patch adds FP64 emulation support for ATS-M.
Introducing new environment variable - NEO_FP64_EMULATION - which provides
an option to allow the opt-in emulation of FP64.
When emulation is enabled, we pass -cl-fp64-gen-emu (ocl) /
-ze-fp64-gen-emu (L0) as an internal option to IGC.

When using ReturnSubDevicesAsApiDevices=1 to have
sub-devices-as-root-devices, then the driver should read the values
passed in the mask as those corresponding to the physical
sub-devices.
For instance, in a dual system with multi-tile device, we would have:
card 0, tile 0
card 0, tile 1
card 1, tile 0
card 1, tile 1
With:
ReturnSubDevicesAsApiDevices=0
ZE_AFFINITY_MASK=0,1
Then all tiles in card 0 and card 1 need to be exposed.
With:
ReturnSubDevicesAsApiDevices=1
ZE_AFFINITY_MASK=0,3
Then card 0 tile 0, and card 1 tile 1 need to be exposed.
