Write tests for np.random.functions

[reazulhoque]

In this PR we have added a collection of np.random functions. We need to complete writing tests for them.

The inital functions already have tests. (https://github.com/reazulhoque/numba-dppy/blob/feature/numpy_random/numba_dppy/tests/test_dpnp_functions.py#L270). This can be followed for the later tests.

We need to write tests for all functions present in: https://github.com/reazulhoque/numba-dppy/blob/feature/numpy_random/numba_dppy/dpnp_glue/dpnp_randomimpl.py

Some np.random functions might produce the following error and we need to skip them for now:

terminate called after throwing an instance of 'oneapi::mkl::unsupported_device'
  what():  oneMKL: rng/generate: Intel(R) Graphics [0x9bca] is not supported
