By modifying functions to accept a PyPathLike argument, we saw the side-effect of disabling implicit conversions. In an alternative branch, we tried to re-enable implicit conversion by adding new functions with a PyPathLike argument. This worked, but had drawbacks: * the signatures become redundant, and some post-processing must be implemented * the implicit conversion works fine, but only with a string argument. Much better would be to supply a PyPathLike This patch leaves the modifications of function arguments and simply adds the missing icon.addPixmap(PyPathLike). Other implicit conversions which might be found missing should be added the same way. [ChangeLog][shiboken6] The implicit conversion of icon.addPixmap(str) was replaced by an explicit version which takes PyPathLike.
