Add buf parameter of matrix layout convertion functions

[primenumber]

This PR adds new parameter to row_major_to_col_major and col_major_to_row_major.
New parameter is buffer pointer to store elements of new matrix.
Caller of the function have to manage the buffer, we can use std::unique_ptr<T>.

Motivation and Context

row_major_to_col_major and col_major_to_row_major allocate new buffer in function, this behavior may cause memory leak and difficult to optimize memory use.
