radv: Remove #7487 workaround

[AniLeo]

Mesa fixed the issue that caused a performance regression, worked around in RPCS3 on #7487. The source of the issue was a lack of clarification on the Vulkan specification itself, which has also been added as of Vulkan 1.2.134 @ KhronosGroup/Vulkan-Docs@b275361#diff-267e1eca473d7e2ecbce0bc657a44d37R1465

The bug fix commit has been part of upstream mesa since 20.0.2:
https://gitlab.freedesktop.org/mesa/mesa/-/commit/aa3fe28d05316a83637d8ecca71ed75c6977767f

It has been decided to wait out a few weeks for distros to push the new mesa to their repositories (f. ex: arch's mesa is still on 19.3.4, with 20.0.2 still on Testing) and for users to be able to upgrade

Noted. Will update.

[Leopard1907]

Fwiw , users with Ubuntu 18.04 based distros should be ok too if they use this PPA that Valve maintains. It is on 20.0.2 too.

If users will be required to update their mesa version, such as ubuntu 18.04 users, to use the application properly it would probably be wise to add a warning in the app to add this ppa and/or make a note about it in the quickstart guide.

It should be as simple as telling them to:

sudo add-apt-repository ppa:kisak/kisak-mesa
sudo apt upgrade
Then reboot.

The lutris wiki is a good source as well for getting updated video drivers on a linux distribution.

I wonder if we can bundle the updated mesa with the appimage, or if thats too far fetched.

I have added the fix for this in with another workaround for Nvidia GPUs that I was told was fixed.
