Disallow numeric scalar conversation for non-0D arrays

[vlad-perevezentsev]

This PR partially aligns usm_ndarray scalar conversion semantics with the Python Array API by allowing numeric scalar conversion only for 0D usm_ndarrays

Conversions to Python numeric scalars via int, float, complex and their corresponding methods (__int__, _float__, __complex__) now raise TypeError when applied to usm_ndarrays with ndim !=0

Note:
For full compliance with the Python Array API, the same check should be used for truth values __bool__ method and integer indexing index method
But these changes would impact dpnp compatibility with Numpy 2.4 which currently disallows only numeric scalar conversation (a minor behavioral difference I think)
In addition several dpctl tests rely on implicit truth conversion for non-0D arrays and must be updated accordingly
