emulators/wine-devel: Add wow64 support

[monwarez_mailoo.org]

Summary

This is a patch of wine-devel to add wow64 support.

It is mostly adapted from https://gitlab.winehq.org/wine/wine/-/merge_requests/8073 and updated to work on wine-devel 11.7

The current blocker is intel igpu for 32bit that got fixed by this commit in drm-kmod:

https://github.com/freebsd/drm-kmod/commit/a72c05b22dc21e4a68b0146d85d1ec0be4470931

Technically just returning gtt >= 4 is enough on 15.0 too.

So once 15.1 is out, we can start having wine-devel using the new wow64 mode since at least one release will have full support, and the older version will also have new wow64 working except for the intel igpu case (and on 32bit graphical application).

This is the final working version for new wow64

I am very happy and very supportive of this change and believe it can go
in soon – hopefully getting key FreeBSD-specific changes upstream (or at
least submitted upstream).

My recommendation is to focus on getting dlls/ntdll/unix/signal_x86_64.c
upstream and at least submitting the configure.ac changes. Then I'd feel
comfortable approving this patchset (presumably for Wine 11.8 then)?

Could this go upstream independently? Not to hold off this overall changset, it just seems important not to carry something like this locally, so at least seeing it submitted upstream seems important.

This file is currently (for about a week) broken upstream after changes by Alexandre that only work on Linux and macOS.

My strong recommendation is to focus on this, get it upstream (so that no local patch to this file is required) and then make the switch. Carrying a local patch of this complexity and size looks like a big maintenance risk.
