Fix for PCH-less build after wake up changes.

Include wx/msw/private.h when not using PCH to get wxZeroMemory() (this makes
it unnecessary to include wx/msw/wrapwin.h as it's already included by the
other header).

Fix wxStringTokenizer copy ctor and assignment operator.

Implement copying of wxStringTokenizer correctly: compiler-generated versions
didn't work as the position of the tokenizer didn't point into the correct
string after making the copy.

Fix this by adjusting the position iterator to use the copy of the string.

Closes #16339.

Draw cursor image in wxCursorProperty using wxDC::DrawBitmap.

Since monochrome images are supported by wxBitmap (under MSW) there is no longer need to draw cursor image using native Win API.
