chore(conda): enable strict channel priority for conda build

[gforsyth]

This PR enables strict channel priority for building conda packages with conda-build.

xref rapidsai/build-planning#84

[gforsyth]

It isn't going to be possible to use strict priority with some cuda11 builds because of libcufile versions spread across conda-forge and nvidia (newer version are all available on conda-forge but older versions are only on nvidia).

I'll have to update the build scripts to not set strict priority for 11.8 builds on x86_64

Thanks Gil! 🙏

Do we need similar changes for testing?

kvikio/ci/test_cpp.sh

Line 18 in a4170fc

rapids-mamba-retry env create -qy -f env.yaml -n test

kvikio/ci/test_python.sh

Line 23 in a4170fc

rapids-mamba-retry env create -qy -f env.yaml -n test

Edit: And doc builds?

kvikio/ci/build_docs.sh

Line 20 in a4170fc

rapids-mamba-retry env create -yq -f env.yaml -n docs

[gforsyth]

I think I'm going to hold off on those for a follow-up, because it's also going to involve removing channels from dependencies.yaml and some changes upstream in gha-tools

[jakirkham]

In that case, could you please note this in the OP of issue ( rapidsai/build-planning#84 )?

Since it sounds like we need two passes of all RAPIDS projects to implement this, would also update the checklist to reflect this is part 1

[msarahan]

Not terribly important, but this boilerplate seems like it could be added to a function in gha-tools to reduce the copy-paste stuff.

[gforsyth]

Yep, strong agree -- I have a draft PR open for that here rapidsai/gha-tools#153 but I didn't want to merge it in mid-release.
I think I'm going to hold off on any more channel priority PRs until I can change things more easily.

This is waiting for rapidsai/gha-tools#153, which is waiting until after the 25.04 release.
