2947877871 [move sift.cpp] Merge pull request opencv/opencv_contrib#2301 from ab-dragon:conditionally_compute_dog_pyramid 
Build DoG Pyramid if useProvideKeypoints is false

The buildDoGPyramid operation need not be performed unconditionally. In cases where it is not needed, both memory and speed performance can be improved

0ed3209b00 ocl: avoid unnecessary loading/initializing OpenCL subsystem 
If there are no OpenCL/UMat methods calls from application.

OpenCL subsystem is initialized:
- haveOpenCL() is called from application
- useOpenCL() is called from application
- access to OpenCL allocator: UMat is created (empty UMat is ignored) or UMat <-> Mat conversions are called

Don't call OpenCL functions if OPENCV_OPENCL_RUNTIME=disabled
(independent from OpenCL linkage type)

[GSOC] Enable OCL for AKAZE (#9330)

* revert e0489cb - reenable OCL for AKAZE

* deal with conversion internally in AKAZE

* pass InputArray directly to AKAZE to allow distiguishing input Mat/UMat. deal with conversion there
* ensure that keypoints orientations are always computed. prevents misuse of internal AKAZE class.

* covert internal AKAZE functions to use InputArray/OutputArray

* make internal functions private in AKAZE

* split OCL and CPU paths in AKAZE

* create 2 separate pyramids, 1 for OCL and 1 for CPU
* template functions that use temporaries to always store them as correct type (UMat/Mat)

* remove variable used only in OCL path

causes unused variable warning

* update AKAZE documentation

* run ocl version only when ocl is enabled

* add tests for OCL path in AKAZE

* relax condition for keypoints angle
