Update Chisel 7 version to 7.13.0 - #2348

Conversation
Updating to a recent Chisel 7 version pulls in chipsalliance/chisel#5099, which causes source incompatibilities in Rocket Chip. That was fixed in chipsalliance/rocket-chip#3775, so I bumped that submodule to the latest. That in turn causes an incompatibility with Shuttle. That was fixed in ucb-bar/shuttle#15, so I bumped that submodule to latest. Updating to a non-RC version of Chisel 7 also causes linking errors with json4s, as mentioned in chipsalliance/chisel#4955. So I've updated the version of json4s-jackson that Rocket Chip uses during the Chisel 7 build.
