Kernel to interleave the elements of a matrix.
This function puts the values in a 4x4 block of Matrix A on the same row (Interleaved values)
\[ \left( \begin{array}{cccc} a00 & a01 & a02 & a03 \\ a10 & a11 & a12 & a13 \\ a20 & a21 & a22 & a23 \\ a30 & a31 & a32 & a33 \\ \end{array} \right) \rightarrow \left( \begin{array}{ccccccccccccccccc} a00 & a10 & a20 & a30 & a01 & a11 & a21 & a31 & a02 & a12 & a22 & a32 & a03 & a13 & a23 & a33 \\ \end{array} \right) \]
After this operation, the dst matrix will have the following shape: [ height * 4, ceil(width / 4.0f) ]
