Rewite polar transforms (#11323) 
* Rewrite polar transformations

- A new wrapPolar function encapsulate both linear and semi-log remap
- Destination size is a parameter or calculated automatically to keep objects size between remapping
- linearPolar and logPolar has been deprecated

* Fix build warning and error in accuracy test

* Fix function name to warpPolar

* Explicitly specify the mapping mode, so we retain all the parameters as non-optional.

Introduces WarpPolarMode enum to specify the mapping mode in flags

* resolves performance warning on windows build

* removed duplicated logPolar and linearPolar implementations

Avoiding Divide By Zero Error 
In line 104 `if ( full_neg_lst[i].cols >= box.width && full_neg_lst[i].rows >= box.height )` removed '=' as it causes divide By Zero Error in line 106 and 107 `box.x = rand() % ( full_neg_lst[i].cols - size_x );` when  full_neg_lst[i].cols = size_x or full_neg_lst[i].rows - size_y
