core: eliminate coverity scan issues (#14162)

* core(hal): avoid using of r,g,b,a parameters in interleave/deinterleave

- static analysis tools blame on possible parameters reordering
- align AVX parameters with corresponding SSE/NEO/VSX/cpp code

* core: avoid "i,j" parameters in Matx methods

- static analysis tools blame on possible parameters reordering

* core: resolve coverity scan issues
