Add ndarray subclassing support via `ndarray.view()` method (#2815)

The PR adds ndarray subclassing support via `ndarray.view()` method.

It implements the `type` parameter in `dpnp.ndarray.view()` to enable
custom subclasses, matching NumPy/CuPy behavior. Also includes proper
`__array_finalize__` hook invocation for metadata propagation.

The implementation is done through `_view_impl()` helper using
'array_class' parameter to avoid shadowing builtin 'type'.
The tests scope is extended with new 7 tests for verifying subclassing
support and enabling `TestSubclassArrayView` class from third party
tests.

This PR closes #2764.
