The gfx803 "Fiji" device was deprecated in GCC 14, removed from LLVM 18, and
hasn't worked properly with the drivers since about ROCm 4.
This patch removes the device from GCC options and documentation, and removes
the direct mentions from the internals.
The TARGET_GCN3 support in the back-end is now unused and can be removed (in a
follow-up patch).
