Update Wine Wayland driver to 8.0-rc4 and add update instructions

winewayland driver development's future is upstream - see https://github.com/wine-mirror/wine/commits/master/dlls/winewayland.drv
So that part can be dropped as it's unlikely that repo will get updated anymore. The only possibly useful case would be to check and - if needed - rebase the patchset against Proton 8. But that's about it for winewayland :)

[orowith2os]

Not everything is upstream yet, so I want to keep this patch going until it is, at which point this can be removed and newer builds can just use the Wine upstream that contains the driver.

If I recall correctly Alexandros should be rebasing his wayland patches on top of what he has upstream already in this branch:
https://gitlab.winehq.org/afrantzis/wine/-/tree/wayland?ref_type=heads

Currently part4 got merged, so we would have to wait for it to be rebased on that.

[Riesi]

Not all is upstream already.
So one would have to update the community patch every time upstream gets a patch in and the downstream was rebased.

@Riesi That branch hasn't been updated in over 3 months now though (so I'm doing my own rebases)

Is there any chance this can be rebased (ideally in some Proton-compatible way)? I've tried several ways myself, but I don't know enough about Wine/Proton's internals to make it work.

I did manage to get a normal Wine build working (based on the original wine-8.2 branch). In my testing, it improves the NVIDIA+Wayland experience a lot.

The full upstreaming is still a long ways off, and then some more time for it to trickle down to Proton.

@gnusenpai I'm not at home, and won't be until the end of the month, so if I do rebase these, it'll probably take a while (unless the original patch creator rebases this themselves, and I generate one).

For now, it's not the best workaround, but just use an Xorg session.
