\brief Compute the modular inverse: X = A^-1 mod N
\param X The destination MPI. This must point to an initialized MPI. \param A The MPI to calculate the modular inverse of. This must point to an initialized MPI. \param N The base of the modular inversion. This must point to an initialized MPI.
\return \c 0 if successful. \return #MBEDTLS_ERR_MPI_ALLOC_FAILED if a memory allocation failed. \return #MBEDTLS_ERR_MPI_BAD_INPUT_DATA if \p N is less than or equal to one. \return #MBEDTLS_ERR_MPI_NOT_ACCEPTABLE if \p A has no modular inverse with respect to \p N.
