Branch 23.10 merge 23.08

This PR migrates RMM to use `fetch_rapids.cmake` like most RAPIDS repos. This makes it easier to define a single source if the upstream branch of rapids-cmake needs to change for testing, like in rapidsai#1247.

This PR contains the minimal set of changes to compile using Cython 3 without warnings. Future PRs can be made to take advantage of new or improved features.

The specific changes are:
- Ensuring `nogil` always comes after `except`. `except * nogil` is a compile-time error in Cython 3
- Adding `noexcept` or `except *` to any `cdef ` functions missing them. In Cython 0.29 these would default to `noexcept`, which meant that exceptions would not be properly propagated. In Cython 3.0.0, these default to `except *`, which incurs a performance penalty for reacquiring the GIL to check the exception value even for `nogil` functions. Being explicit here is important.

There are a large number of outstanding warnings due to NVIDIA/cuda-python#44. cuda-python for CUDA 12 has the necessary fix, but we will need a cuda-python 11.8.* bugfix with a backport to make those warnings go away.

Forward-merge branch-23.08 to branch-23.10

The latest versions `4.1` and `4.0` of `sphinxcontrib-jquery` have an issue with jQuery installed currently in sphinx. This is causing the search functionality to fail so I've pinned the version to `3.0.0`, this resolves the issue.
