Used clang-format off, clang-format on to avoid include reordering

[oleksandr-pavlyk]

Fixed clang-format induced issue with ordering of includes in the pybind11 example.

The "dpctl_sycl_types.h" must be included before dpctl's CPython API headers (e.g. _sycl_queue_api.h). Otherwise compilation errors with DPCTLSyclQueueRef is underfined.

Implemented two more functions, retrieving useful device properties, such as Global and local memory size in bytes. (see #587)
