Merge pull request #16805 from Volskig:mp/ocv-gapi-standalone-scalar

G-API: Unification of own:: Scalar with cv:: Scalar

* cvdefs.hpp

* Small changes

* Deowned Scalar. Does't work

* Something

* Removed to_ocv for Scalar

* Clear code

* Deleted whitespaces

* Added include<..own/scalar.hpp in cvdefs.hpp.

* Long string split on two now

* Comment about scalar

* Comment about crutch

* Removed second varible in scalar_wrapper

* Changed wrapper for scalar, alignment

* Alignment

* Whitespaces

* Removed scalar_wrapper
