feature: Affinity mask plus ReturnSubDevicesAsApiDevices

Browse Source 
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.
