Arch property struct types are created at runtime. Go has a limit
of 2**16 bytes for the name of a type, and the type of a struct
created at runtime is a string containing all the names and types
of its fields. To avoid going over the limit, split the runtime
created structs into multiple shards.
Also undo MoreBaseLinkerProperties now that it is no longer
required.
