The ShardsvrCreateCollectionCommand::Invocation::typedRun method in src/mongo/db/s/shardsvr_create_collection_command.cpp should prohibit sharding on any FLE2 ESC, ECC, or ECOC collections. These collections can be identified because they start with "fle2." and endwith one of [".esc", ".ecoc" or ".ecc"].

This restriction will be added for now to reduce the complexity sharded encrypted compact.
