Extend ._tensor_impl with where(), clip() and type utils functions (#2778)

This PR extends `_tensor_impl` in `dpctl_ext.tensor` with the `_where,
_clip` and repeat functions
(`_repeat_by_sequence, _repeat_by_scalar`)

It also adds `repeat(), where(), clip()` and `can_cast, finfo, iinfo,
isdtype, result_type` from `_type_utils.py` `to dpctl_ext.tensor and
updates the corresponding dpnp functions to use these implementations
internally
