[G-API]: findContours() and boundingRect() Standard Kernels Implementation
* Add findContours() standard kernel
- API and documentation provided:
- as OpenCV provides two overloads whether to calculate hierarchy or not, but they differ by only the output in sight of G-API, two different G-API functions and kernels implemented
- G-API Imgproc documentation divided into more parts according to imgproc module parts
- some typos connected with division into parts corrected
- `GArray<GArray<U>>` overload for `get_out` function provided to coonvert correctly into `vector<vector<U>>`
- OCV backend supported
- accuracy tests provided
* Add boundingRect() standard kernel
- API and documentation provided:
- GOpaque<Rect> used as an output
- as OpenCV provides two possibilities whether to take a gray-scale image or a set of 2D points (`Point2i` or `Point2f` supported), three different overloads of a single G-API function and three kernels implemented
- for a gray-scale image the overload via `GMat`
- for a set of `Point2i` - the one via GArray<`Point2i`>
- set of `Point2f` -> GArray<`Point2f`>
- OCV backend supported
- accuracy tests provided
- comparison function for Rects provided
- some typos in `gapi_tests_common` corrected
* Fix precommit windows warnings
* - Addressing comments:

* Static_cast for warnings
* - Remove randomness
- Fix unnecessary precision losses
* - Forgot reference for RNG
* addressing comments
* equalizeHist -> no group
* `const` addedin new functions
* Address suggestions:
- Hierarchical -> H
- added cv::GMatDesc::isVectorPoins()
- added support of giving a set of points to boundingRect()
* Addressing comments
- IoU comparison function added for Rects
- isPointsVector moved from a GMatDesc method to a separate function in imgproc.hpp
- enums instead of int
- typos corrected
* Addressing comments
- findContours: Point offset -> GOpaque<Point>
- removed "straight" comparison for Rects, IoU available only
- changed vectors initialization -> fix Debug test run
- Some typos
* added comment for later upgrades
* Fix not to corrupt docs by FIXME
* Addressing commens
- overload without offset added (as a temporary workaround)
- checkMetaForFindingContours -> validateFindingContoursMeta
- added ostream overload for enums used in tests
[G-API]: morphologyEx() Standard Kernel Implementation
* cv::gapi::morphologyEx() kernel
- implemented (without separate 3x3 version)
- tests added: check only different operations, not kernels/borders
* Address comments: add `const` where needed
* Replaced fundamental tyeps -> enums where needed
- added operator<< overload for cv::MorphTypes for tests output
* G-API: Introduce ONNX backend for Inference
- Basic operations are implemented (Infer, -ROI, -List, -List2);
- Implemented automatic preprocessing for ONNX models;
- Test suite is extended with `OPENCV_GAPI_ONNX_MODEL_PATH` env for test data
(test data is an ONNX Model Zoo repo snapshot);
- Fixed kernel lookup logic in core G-API:
- Lookup NN kernels not in the default package, but in the associated
backend's aux package. Now two NN backends can work in the same graph.
- Added Infer SSD demo and a combined ONNX/IE demo;
* G-API/ONNX: Fix some of CMake issues

Expand ie::Params to support config
* Add config to IE params
* Add test
* Remove comments from tests
* Rename to pluginConfig
* Add one more overloads for pluginConfig
* Add more tests
- cv::gapi::serialize bypasses compile arguments which have no S11N specialization with serialize/deserialize callbacks for underlying types
- cv::gapi::deserialize can accept arbitraty number of serialized compile args in a stream but will return only those which are requested by user via template parameter pack if they are presented in the stream. If some or all of them are not presented cv::gapi::deserialize will ignore and return only those which are presented
- cv::gapi::deserialize can accept only types which can be deserialized (have S11N<T> specialization with the user callbacks)
- Added cv::gapi::s11n::detail::has_S11N_spec<T> trait to separate compile arguments which have S11N<T> specialization with the user callbacks
- desync() is a new (and for now, the only one) intrinsic
which splits the graph execution into asynchronous parts
when running in Streaming mode;
- desync() makes no effect when compiling in Traditional mode;
- Added tests on desync() working in various scenarios;
- Extended GStreamingExecutor to support desync(); also extended
GStreamingCompiled() with a new version of pull() returning a
vector of optional values;
- Fixed various issues with storing the type information & proper
construction callbacks for GArray<> and GOpaque;
- Introduced a new infer(Roi,GMat) overload with a sample;
- Introduced an internal API for Islands to control fusion
procedure (to fuse or not to fuse);
- Introduced handleStopStream() callback for island executables;
- Added GCompileArgs to metadata of the graph (required for other
features).
