[shuffle] Move utils to new structure.
The name `core` was decided fit better with the base language for the
IR. This CL moves the `core/` folder to `utils/` and moves the files
into the correct subdirectories. The build targets and namespaces are
not updated as part of the move and will be fixed up in later CLs.
