gapi: Full calcOpticalFlowPyrLK implementation (2 overloads) and tests

Browse Source 
- opencv_gapi module is linked with opencv_video module (optional dependency)
     - kernels added to a new cv::gapi::video namespace and a brand new files created to provide gapi_video environment
     - there are 2 different kernels as G-API should provide GMat AND GArray<GMat> implementation: cv::calcOptFlowPyrLK doesn't calculate pyramids if vector<Mat> is given so just the cast GMat -> GArray<GMat> wouldn't represent all the cv:: functionality
     - tests to check both kernels (based on cv::video tests for cv::calcOpticalFlowPyrLK())
     - tests for internal purposes added
     - vectors<T> comparison in tests implemented
     - new (and old too) common test structures refactored to avoid code copypasting
     - "modules/gapi/test/common/gapi_video_tests_common.hpp" created to share some code snippets between perf and acc tests and avoid code copypasting

/** @brief Calculates an optical flow for a sparse feature set using the iterative Lucas-Kanade
method with pyramids.
See @cite Bouguet00 .
@note Function textual ID is "org.opencv.video.calcOpticalFlowPyrLK"
@param prevImg first 8-bit input image (GMat) or pyramid (GArray<GMat>) constructed by
buildOpticalFlowPyramid.
@param nextImg second input image (GMat) or pyramid (GArray<GMat>) of the same size and the same
type as prevImg.
@param prevPts GArray of 2D points for which the flow needs to be found; point coordinates must be
single-precision floating-point numbers.
@param predPts GArray of 2D points initial for the flow search; make sense only when
OPTFLOW_USE_INITIAL_FLOW flag is passed; in that case the vector must have the same size as in
the input.
@param winSize size of the search window at each pyramid level.
@param maxLevel 0-based maximal pyramid level number; if set to 0, pyramids are not used (single
level), if set to 1, two levels are used, and so on; if pyramids are passed to input then
algorithm will use as many levels as pyramids have but no more than maxLevel.
@param criteria parameter, specifying the termination criteria of the iterative search algorithm
(after the specified maximum number of iterations criteria.maxCount or when the search window
moves by less than criteria.epsilon).
@param flags operation flags:
- **OPTFLOW_USE_INITIAL_FLOW** uses initial estimations, stored in nextPts; if the flag is
not set, then prevPts is copied to nextPts and is considered the initial estimate.
- **OPTFLOW_LK_GET_MIN_EIGENVALS** use minimum eigen values as an error measure (see
minEigThreshold description); if the flag is not set, then L1 distance between patches
around the original and a moved point, divided by number of pixels in a window, is used as a
error measure.
@param minEigThresh the algorithm calculates the minimum eigen value of a 2x2 normal matrix of
optical flow equations (this matrix is called a spatial gradient matrix in @cite Bouguet00), divided
by number of pixels in a window; if this value is less than minEigThreshold, then a corresponding
feature is filtered out and its flow is not processed, so it allows to remove bad points and get a
performance boost.
@return GArray of 2D points (with single-precision floating-point coordinates)
containing the calculated new positions of input features in the second image.
@return status GArray (of unsigned chars); each element of the vector is set to 1 if
the flow for the corresponding features has been found, otherwise, it is set to 0.
@return GArray of errors (doubles); each element of the vector is set to an error for the
corresponding feature, type of the error measure can be set in flags parameter; if the flow wasn't
found then the error is not defined (use the status parameter to find such cases).
