Merge pull request #19685 from danbey:setting_stereoBMImpl_in_init_list 
Init params (StereoBMParams) in StereoBMImpl constructor initialization list

* Init StereoBMImpl in initialization list

To improve preformence it is better to init the params (StereoBMImpl) in the
initialization list.

* coding style

* drop useless copy/move ctor

55cdeaa6dd BufferArea: initial version, usage in StereoBM 
New class BufferArea is used to hide complexity of buffers allocations and allow instrumentation with valgrind and sanitizers.

1e9ad5476d core(intrin): drop hasSIMD128 checks 
- use compile-time checks instead (`#if CV_SIMD128`)
- runtime checks are useless

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)

0e9c8e2dd5 'resolves' 6898 
I have seen that you can input a Mat_<float> on StereoBM, but the value seems the same as CV_16S.
I changed it so, only if you input a Mat_<float> it makes use of a previously truncated 4 bits, giving more resolution to Disparity Matrix. (The algorithm stays the same, it's not more precise).
If any other input Mat is given, it changes nothing.

45958eaabc Implementation detector and selector for IPP and OpenCL; 
IPP can be switched on and off on runtime;

Optional implementation collector was added (switched off by default in CMake). Gathers data of implementation used in functions and report this info through performance TS;

TS modifications for implementations control;

8a4a1bb018 Several type of formal refactoring: 
1. someMatrix.data -> someMatrix.prt()
2. someMatrix.data + someMatrix.step * lineIndex -> someMatrix.ptr( lineIndex )
3. (SomeType*) someMatrix.data -> someMatrix.ptr<SomeType>()
4. someMatrix.data -> !someMatrix.empty() ( or !someMatrix.data -> someMatrix.empty() ) in logical expressions
