G-API: Fix Journal usage in Fluid backend (#15238)

* Fix Journal usage in Fluid backend

* Delete dumpDotRequired(): invalid check

* Update mem consumption test

* Test that new test works

* Debug memory consumption function

* Increase iterations in test

* Re-write memory consumption measurement part

* Restore correct fix for Fluid journals

Segmentation module (#15082)

* G-API: rename ArgKind OPAQUE to GOPAQUE

Rename ArgKind value to GOPAQUE to fix conflict in the
user code when wingdi.h is included: it defines OPAQUE
macro that (for some reason) is chosen instead of ArgKind
value

* Add compatibility with existing API

* Renamed GOPAQUE to OPAQUE_VAL

* Determine input shapes

* Add test

* Remove getInputShapes

* Fix model

* Fix constructors

* Add Caffe test

* Fix predict

* WINCE 8.0 requires ARMv7 Thumb2 and thus have NEON instructions

* Only add NEON if on _ARM_

Convert HOG from SSE SIMD to HAL - 35-45% faster on Power (VSX) (#15199)

* Convert SSE SIMD to HAL. 35-45% improvement for Power (VSX)

* Remove CV_NEON code. Use v_floor instead of 3 lines of code.

* Invert comparison logic to simplify code.

* Change initialization from v_load to constructor type.

* Remove unavoidable print of CV error

The return value covers whether the device exists.

This might be better hidden behind a debug flag, but I couldn't work out how to do that nicely.

* Use `CV_LOG_WARNING` macro to log rather than removing it entirely

  * add -Wno-psabi when using GCC 6
  * add -Wundef for CUDA 10
  * add -Wdeprecated-declarations when using GCC 7
  * add -Wstrict-aliasing and -Wtautological-compare for GCC 7
  * replace cudaThreadSynchronize with cudaDeviceSynchronize

Support new IE API (#15184)

* Add support OpenVINO R2 for layers

* Add Core API

* Fix tests

* Fix expectNoFallbacksFromIE for ONNX nets

* Remove deprecated API

* Remove td

* Remove TargetDevice

* Fix Async

* Add test

* Fix detectMyriadX

* Fix test

* Fix warning

* in OpenCV.js added 'rotate' function and test sample

* value test added
