Repurposes existing u8 implementations of remap_s16 for Neon and SVE2,
and makes them work for source type u16.

This is intended to catch potential issues in adapters/opencv.

It is necessary to remove -DOPENCV_DISABLE_THREAD_SUPPORT=ON
otherwise the build will fail with a warning about unused function
getNumberOfCPUsImpl.

Use KLEIDICV_MAXIMUM_CHANNEL_COUNT instead of the magic number 4 in some
test code.

Also update signature of remap and warp_perspective functions to avoid
the same mistake there.

cv::Mat doesn't have width or height methods, but has cols & rows
instead.

It seems that the act of polling itself can cause the device to heat up
so do it only every 3 seconds instead of every 1 second.

Some compilers appear to have difficulty optimizing the previous code so
it can impact performance.

Cut-off point changed when to call the multithreaded implementation in
the OpenCV HAL.

For benchmarks with a single parameter parentheses are not needed.

Benchmark suite from OpenCV's video module was added to the benchmark
list, but the related perf test binaries were not pushed by push.sh
