emulators/wine-devel: Invoke with LD_BIND_NOW and revampe WoW

Forward port 1d2af6e0 and its
two follow-up fixes ad15b0e7 and
1b5885c4 from emulators/wine:

   Wine 6.0 and later need LD_BIND_NOW / LD_32_BIND_NOW on FreeBSD,
   cf. https://bugs.winehq.org/show_bug.cgi?id=50257 and
   https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=252307
   so move the actual binaries to wine64.bin / wine.bin and invoke
   them via a script that does those settings. [1]

   Also revamp the WoW handling/packging which combines 32-bit/i386
   Wine into 64-bit/amd64 Wine. [1]
