[util] Add workarounds for Garden Warfare 2

[Blisto91]

Game won't launch with amd vendorId but works with 10de. Everyone on ProtonDB sets it to 1c06 instead which also works, but i couldn't find whose vendorId that was so just went with 10de. Didn't find it to cause any issues from some short testing.

DadSchoorse correctly pointed out disabling nvapiHack was redundant so I've removed that part.

Reworded the comment a bit.

@gofman Figured that the issue is when the game sees a amd gpu it will try to use atiadlxx which it will fail to do. With proton using WINEDLLOVERRIDES="atiadlxx=b" %command% will make it work too. That workaround has been added to experimental bleeding edge now as that was deemed a better solution.
Overwriting the vendorId to 10de will probably make the above override useless. But without 10de the game doesn't launch out of the box on wine versions where the atiadlxx work/override isn't available.

A middle ground would be to allow these vendorId's to also be set through a env var. Then proton could rid this built in config, without the user having to make a dxvk.conf, and make their own workaround work out of the box. But it would still leave this built in workaround for users where that isn't a option.

Or Proton could make their own dxvk.conf on the fly, like it's done in e.g. protonfixes (provides additional per-game configuration on top of Proton, also AFAIK it's integrated in GE builds). If they don't want (or can't have, idk) the whole thing in Proton, they have my permission to freely use my commits from that project (subj).

@pchome Ye that is also possible ofc. I did have it on my mind, but didn't know how practical it was.
But if that method is already in use other places and works fine that's cool 🙂

BTW for single overrides (no separate config file needed) protonfixes supports "aliases" to its builtin functions in command line. So on Proton side such override could be something like
WINEDLLOVERRIDES="atiadlxx=b" -pf_dxvk_set=dxgi.customVendorId=-1 %command%
