Merge pull request #16561 from vpisarev:better_hough_circles 
* improved version of HoughCircles (HOUGH_GRADIENT_ALT method)

* trying to fix build problems on Windows

* fixed typo

* * fixed warnings on Windows
* make use of param2. make it minCos2 (minimal value of squared cosine between the gradient at the pixel edge and the vector connecting it with circle center). with minCos2=0.85 we can detect some more eyes :)

* * added description of HOUGH_GRADIENT_ALT
* cleaned up the implementation; added comments, replaced built-in numeic constants with symbolic constants
* rewrote circle_popcount() to use built-in popcount() if possible
* modified some of HoughCircles tests to use method parameter instead of the built-in loop

* fixed warnings on Windows
