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

Merge pull request #19583 from theroyalpekka:patch-1 
* Update polynom_solver.cpp

This pull request is in the response to Issue  #19526. I have fixed the problem with the cube root calculation of 2*R. The Issue was in the usage of pow function with negative values of R, but if it is calculated for only positive values of R then changing x0 according to the parity of R, the Issue is resolved. Kindly consider it, Thanks!

* add cv::cubeRoot(double)

75ad74c893 ffmpeg/3.4: update FFmpeg wrapper 2021.03

cbfd38bd41 core: rework code locality 
- to reduce binaries size of FFmpeg Windows wrapper
- MinGW linker doesn't support -ffunction-sections (used for FFmpeg Windows wrapper)
- move code to improve locality with its used dependencies
- move UMat::dot() to matmul.dispatch.cpp (Mat::dot() is already there)
- move UMat::inv() to lapack.cpp
- move UMat::mul() to arithm.cpp
- move UMat:eye() to matrix_operations.cpp (near setIdentity() implementation)
- move normalize(): convert_scale.cpp => norm.cpp
- move convertAndUnrollScalar(): arithm.cpp => copy.cpp
- move scalarToRawData(): array.cpp => copy.cpp
- move transpose(): matrix_operations.cpp => matrix_transform.cpp
- move flip(), rotate(): copy.cpp => matrix_transform.cpp (rotate90 uses flip and transpose)
- add 'OPENCV_CORE_EXCLUDE_C_API' CMake variable to exclude compilation of C-API functions from the core module
- matrix_wrap.cpp: add compile-time checks for CUDA/OpenGL calls
- the steps above allow to reduce FFmpeg wrapper size for ~1.5Mb (initial size of OpenCV part is about 3Mb)
