GPU plugin Level Zero support

OpenVINO GPU plugin can be compiled with experimental Level Zero support. When enabled, plugin will use Level Zero as GPU compute API instead of OpenCL.

How to build with Level Zero support

1. Configure cmake with the following additional option:
   • -DGPU_RT_TYPE=L0
2. Build OpenVINO
   • cmake --build . --config Release

How to check what runtime is used

1. Set OV_VERBOSE=1 environment variable
2. Run workload
3. Find what variant of stream is reported in the logs (ze_stream or ocl_stream)
   • Example output for Level Zero runtime: ze_stream: [GPU] Created L0 stream
