Adds a stand-alone resize_util app for testing. The app
will not be built in the shared library configurations
so as not to require the APIs to be exposed.

This avoids fitlering a frame multiple times at the same level.

We don't use different filter kernels for x and y, it is always one kernel
for both directions.

SSE for a 64x64 block with 3 planes can go as high as 3*2^28. So left
shift by 4 may overflow 32 bit int.

Use this method with rt at speed -5.

The sum of squared mv components can go beyond int range for large
 input resolution. This commit changed the type to int64 to avoid
overflow.
