Cycles: oneAPI: Remove separate context workaround

Browse source 
The minimum supported driver version for Blender 5.1 and
5.2 already includes a fix for the underlying issue, so
there is no need to keep the workaround that isolated each
device into a separate DPC++ context when multiple
descrete GPUs or Level-Zero platforms were detected.
It is now removed.

Ref #138384
