emulators/wine-devel: Update to Wine 9.13

This includes the following changes:

• Support for loading ODBC Windows drivers (though we haven't enabled ODBC at this point).
• More user32 data structures in shared memory.
• More rewriting of the CMD.EXE engine.
• Various bug fixes.

On the way remove files/clang/stdarg.h, a copy of clang's stdarg.h which
we have been using while the devel/llvm* ports did not install it (and
some others). This changed for devel/llvm17 with commit b21e6b4de1
seven weeks ago.
