avutil/wchar_filename: re-introduce explicit cast of void* to char*

Fixes compile error on windows with decklink:

In file included from ./libavformat/os_support.h:175,
                 from ./libavformat/internal.h:30,
                 from libavdevice/decklink_common.cpp:25:
./libavutil/wchar_filename.h: In function 'int wchartocp(unsigned int, const wchar_t*, char**)':
./libavutil/wchar_filename.h:59:32: error: invalid conversion from 'void*' to 'char*' [-fpermissive]
   59 |     *filename = av_malloc_array(num_chars, sizeof **filename);
      |                 ~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      |                                |
      |                                void*

Regression since e9e8bea2e79bc3c481a6f81f75f6c871e3e0f367.

Fixes ticket #11103.
