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 prefer allocating memory first by KMD, instead of malloc first.
By default prefer not caching allocations on MTL devices. This results
in allocations being handled with non-coherent pat index.
For integrated devices when caching is not preferred do not allow
direct memory access in CPU domain. For map/unmap operations create
a dedicated memory allocation for CPU access, instead of accessing it
directly, reusing the same logic as when mapping/unmapping local memory.

- 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.
