website: update GCN3 webpage

This commit makes two major updates to the GCN3 webpage:

1.  Removes the majority of the examples and instead points to the
examples in gem5-resources, which are both more up-to-date and
more numerous.  This eliminates the need to update documentation
in two places, and should reduce confusion moving forward.

2.  Updates the GCN3 information to reflect that ROCm 4.0 is now
supported instead of ROCm 1.6, as well as removing the ROCm libraries
that are no longer needed with ROCm 4.0.
