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

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.

This commit adds support for ZEX_NUMBER_OF_CCS flag which can be used
for limiting number of CCS engines
Format is as follows:
ZEX_NUMBER_OF_CCS=RootDeviceIndex:NumberOfCCS;RootDeviceIndex:NumberOfCCS...
i.e. setting Root Device Index 0 to 4 CCS, and Root Device Index 1 To 1 CCS
ZEX_NUMBER_OF_CCS=0:4,1:1

Before performing gpu device reset, first all level zero resources
and gpu device specific resources have to be cleaned up. Also as
after device reset, state of gpu device would be lost.
Hence after performing gpu device reset, level zero device have
to be reinitialized by querying gpu device again.
This change is aimed at reinitializing the level zero resources
after gpu device reset, so that user could continue using level zero
devices after device reset.
