Create amd.json

Initial commit, needing feedback on where to place this and if this is the right method to add

Maybe this link should explain what this option does instead of linking to mesa source.

@tkashkin - I've mainly been following Phoronix with artices like this: https://www.phoronix.com/scan.php?page=article&item=radv-aco-feb2020

@btegs I have a few questions:

• Is this option applicable to native Vulkan games or is it only useful for Wine/DXVK/Proton?
• Do you know any other potentially useful AMD-specific options which can be added to GameHub?
• What does lspci -k | grep -EA3 'VGA|3D|Display' output on your system?
  I want to check loaded kernel modules to automatically disable or hide tweaks that are not applicable to user's GPU.

@tkashkin - I believe this works for all Vulkan games. Both native and Wine/DXVK/Proton. As for other AMD options, I don't have any others at this time. Here's my output from lspci for my Radeon 580 using Mesa from the https://launchpad.net/~kisak/+archive/ubuntu/kisak-mesa PPA in Ubuntu 19.10:
