Implement of dpnp.linalg.slogdet()

[vlad-perevezentsev]

This PR

1. adds a function dpnp.linalg.slogdet() to get sign and logarithm of the determinant of an input array and a private function dpnp.linalg._lu_factor() to compute the LU factorization of a general n x n
   input matrix using oneapi::mkl::lapack::getrf and oneapi::mkl::lapack::getrf_batch.
   The implementation is written as an extension of pybind11 over the necessary LAPACK functions.

2. updates the implementation of the dpnp.linalg.det() function using dpnp.linalg.slogdet()

3. adds support the complex data type for dpnp.diagonal() function
