This fixes an issue where a submodule branch is not included in the
history of the default branch upon first clone (where the clone
recursively fetches the submodule) when the user passes the
`--single-branch` argument to `clone-*`.

There have been a number of changes to RAPIDS builds over the course of
this release and not all changes were fully propagated to the
devcontainers repo. This repo addresses the following:
- As of rapidsai/kvikio#369, kvikio produces
wheels, and rapidsai/kvikio#439 contains
critical fixes that allow the kvikio Python wheel to use the C++
libkvikio wheel. In RAPIDS Python builds we have consistently removed
support for the Python build triggering the C++ build as we have created
C++ wheels since in both conda and pip environments we now expect the
library to be found and we do not need to automatically support the more
esoteric use case of someone turning off build isolation but not having
the C++ library available (devs can handle this case themselves if they
wish). As a result, once rapidsai/kvikio#466 is
merged, the `FIND_KVIKIO_CPP` variable will be completely superfluous
and we can remove that here.
- As of rapidsai/cudf#16640 libcudf no longer
links to libarrow and `USE_LIBARROW_FROM_PYARROW` is no longer used.
- The libcudf and libcuspatial Python package builds in the devcontainer
should (like all other Python packages) omit the CUDA version suffix.
For that, they need to use the `rapids_build_backend_args`.

I always forget this... For
#397 in this case.

Revert change to stop the sccache server between rebuilds.
