…GH-151562) Tcl/Tk 9 may embed the Tk script library in the Tk DLL on Windows. This embedded library is not found by Tcl by default. Mount the loaded Tk DLL as a zipfs archive before calling Tk_Init(), so Tk can find its embedded tk_library using its existing library discovery logic. Preserve Tk_Init()'s normal path if the library is not embedded. (cherry picked from commit c4eb3adbb42d781e2ad35bee5621f1c621c6767b) Co-authored-by: Jonathan J. Helmus <jjhelmus@gmail.com>
