Convert libcudf resource parameters to rmm::device_async_resource_ref

[harrism]

Description

Closes #15498

For reviewers:
Almost all of the thousands of changes are simple textual replace of rmm::mr::device_memory_resource * with rmm::device_async_resource_ref.

I think the only substantial changes that are different are in contiguous_split.cu (which was assigning nullptr to the MR pointer -- I have changed these cases to use a std::optional<rmm::device_async_resource_ref>), and in JNI code.

I still need to figure out how to build and test the JNI bindings. And figure out necessary Cython changes.

JNI is passing CI now. Cython required no changes.

Checklist

• I am familiar with the Contributing Guidelines.
• New or existing tests cover these changes.
• The documentation is up to date with these changes.

It looks like there are some unrelated CI changes in the diff. Could you take a peek?

Definitely are. I have no idea how they got them. Any idea how to remove them, or do I have to start over for the third time?

Note that a local git diff device_async_resource_ref branch-24.06 --stat lists only C++ source and header files, no CI files.

Fixed with a merge.

@harrism Thanks. I think the problem with the diff was that commit 7f49c97 wasn't a normal merge commit that included the history (which is then excluded from the diff, because the branches have common history).

[harrism]

I have added some guidance for reviewers to the description.

[bdice]

I read the first ~200 files and spot-checked the rest. I have one comment on spacing in docstrings. Otherwise, this looks good to me.

(I also looked at contiguous_split.cu specifically as requested.)

[bdice]

A lot of these docstrings have an extra space at the end after rmm::device_async_resource_ref. Can we fix that? e.g.

Suggested change

	* @copydoc cudf::contains(column_view const&, column_view const&, rmm::device_async_resource_ref )
	* @copydoc cudf::contains(column_view const&, column_view const&, rmm::device_async_resource_ref)

[harrism]

Done.

Thank you for the reviews. @bdice thoughts on whether we should proceed with merging this out of sync with other repos? I kind of want to wait until I have a bit more confident progress on other repos, especially RAFT, which is proving kind of tricky.

I'm somewhat inclined to merge sooner, given the scope of this change and its potential for conflicts. It would also be nice to have a large RAPIDS repository using the new code paths, to ensure that it's working as intended. However, if you want to wait, I'm okay with that.

[harrism]

I got the RAFT changes working. Whether they like them is a different matter. But I agree, this PR looks pretty clean and safe, it is reviewed, and at risk of a lot of conflicts, so let's go ahead and merge
