Merge pull request #19580 from SergeyKrivohatskiy:patch-1 
* Fixed OCL implementation of pyrlk

If prevPts size is (N, 1) (which is a default layout for converting `vector<Point2f>` to `UMat`) the `prevPts.cols == 1` and optical flow will be calculated for the first point only.
Getting `prevPts.total()` as in line 1048 is the correct way to get points count.

* fixed compilation warning (size_t to int)

fix link order: put zlib after png/tiff/openexr 
Previous link dependency: imgcodecs --> zlib --> libpng
this can generate imgcodecs shared lib, until Visual Studio integrated
with vcpkg, which will additionally specify LIBPATH, pointing to vcpkg
installed zlib (if any), which links the wrong zlib.

Fixed link dependency: imgcodecs --> libpng --> zlib
in this fixed case, symbols in zlib referenced in libpng will be found
in the build-from-source static zlib, instead of the vcpkg one.

Merge pull request #19486 from fpetrogalli:dotprod_fast-3.4 
* [hal][neon] Optimize the v_dotprod_fast intrinsics for aarch64.

On Armv8 in AArch64 execution mode, we can skip the sequence

   v<op>_<ty>(vget_high_<ty>(x), vget_high_<ty>(y))

in favour of

   v<op>_high_<ty>(x, y)

This has better changes for recent compilers to use less data movement
operations and better register allocation. See for example:

6c1a433c4c python: also catch general c++ exceptions 
they might be thrown from third-party code (notably Ogre in the ovis
module).
While Linux is kind enough to print them, they cause instant termination
on Windows.
Arguably, they do not origin from OpenCV itself, but still this helps
understanding what went wrong when calling an OpenCV function.
