Merge pull request #14828 from armenpoghosov:parmen_RANSACPointSetRegistrator_getSubset_disaster_cleanup

Parmen ransac point set registrator get subset disaster cleanup (#14828)

* Avoid using v_signmask universal intrinsic and mark it as deprecated

* Renamed v_find_negative to v_scan_forward

Crosscorr cleanup (#14936)

* Simplify code for convolution destination type/size

For the 2d filter code, destination size equals source size, and the
crossCorr function even (re-)creates the output matrix with the given size.

The number of channels also have to match. The destination type() is the
one used to create the output matrix, so we can use its type() here.

This is a preparatory patch.

* Remove redundant destination size and type parameters from crossCorr

All calling sites of crossCorr already use (...,
mat, mat.size(), mat.type(), ...), so the parameters are redundant.

Due to the explicitly declared copy constructor Vec<T, n>::Vec(Vec <T,n>&)
GCC 9 warns if there is no assignment operator, as having one typically
requires the other (rule-of-three, constructor/desctructor/assginment).

As the values are just a plain array the default assignment operator does
the right thing. Tell the compiler explicitly to default it.
