anv,radv: Disable VK_EXT_pci_bus_info
The Vulkan working group recently discovered that we made a mistake in assuming that PCI domains are 16-bit even though they can potentially be 32-bit values. To fix this, the next spec update will change the types in the VK_EXT_pci_bus_info struct to be 32 bits which will be a backwards-incompatible change. Normally, Khronos tries very hard to never make backwards incompatible changes to specs. Hopefully, the extension is new enough (2 months) that there are no shipping apps which use the extension so this should be safe. This commit disables the extension for both anv and radv in mesa and should be back-ported to 18.3 ASAP so we avoid any potential issues with new apps running on old drivers. I'll send out a commit (which we can also back-port to 18.3 if we really care) to re-enable the extension in both drivers once this week's spec update ships. The one known use of this extension is internal to mesa and will continue working with the extension disabled and will naturally update when we get a new header.
