NEON 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 output matrix will have the following shape: [ height * 4, ceil(width / 4.0f) ]

Initialise the kernel's input and output.
[in] | input | Input tensor. Data types supported: U8/S8/U16/S16/F16/U32/S32/F32 |
[out] | output | Output tensor which stores the interleaved matrix. Data type supported: same as input . |

Execute the kernel on the passed window.
[in] | window | Region on which to execute the kernel. (Must be a region of the window returned by window()) |
Implements ICPPKernel.
