I think we have exhausted all of the reasonably plausible scenarios. Your hardware appears to be properly configured and you have plenty of PCI lanes available.Enabled IGPU in BIOS and removed the RX580. Boot hung at the same "Start ReadKernalCache" line.
My suggestion now would be to attempt a fresh (and temporary) installation on an external SATA SSD or other internal or external disk.
Reason: There might be problems in your /System/Library/Extensions folder or some other needle in a haystack. Rather than track it down, a fresh installation by strictly following the Build Guide might be the fastest path to a working system.
It shouldn’t take long, but it will require an hour or two.
Of course if someone has an alternative suggestion, please offer it.
