emulators/wine-devel: Update to Wine 6.16

This includes the following changes:

• Initial version of a HID-based joystick backend.
• Improved high-DPI theming support.
• More preparation work for the GDI syscall interface.
• Better CodeView support in WineDump.
• Various bug fixes.

It also addresses a couple of FreeBSD-specific build issues I had to
address due to system headers not including others actually required:

nsiproxy: Include sys/param.h.
nsiproxy: Include netinet/in_pcb.h.
nsiproxy: Include stddef.h.
ntdll: Always return a value in get_builtin_init_funcs.
nsiproxy: Include sys/types.h from udp.c.
nsiproxy: Add $(PROCSTAT_LIBS) to EXTRALIBS.
nsiproxy: Include netinet/in.h in udp.c.
nsiproxy: Include sys/queue.h from tcp.c.

My patch files/patch-dlls-nsiproxy.sys has been integrated upstream,
so remove it here.
