Use latest rattler-build for conda packaging

[vyasr]

Install and verify the latest stable conda-forge rattler-build before C++ and Python conda packaging, allowing cuVS to migrate independently of the shared CI image pin.

The explicit installation of the latest stable rattler-build version in the build scripts is temporary. The installer and its calls will be removed as soon as the shared RAPIDS CI images are updated to provide the upgraded version.

Replace the libcuvs recipe cache with a staging output while preserving all package splits. Explicitly forward the CUDA version, benchmark architecture, and sccache configuration required by isolated build scripts, including the CPU benchmark. Declare direct native library owners for split outputs and CPU benchmarks while preserving their existing dependency contracts.

Related to rapidsai/build-planning#259.

📝 Summary

Summary by CodeRabbit

• Chores
  • Updated C++ and Python build setup to use the latest stable build tool and verify the installed version.
  • Refined package build settings to pass through CUDA and cache configuration.
  • Updated runtime dependencies for CPU benchmarks, shared libraries, tests, examples, and ANN benchmarks, including platform-specific dependencies for Linux and ARM systems.

The CI build scripts now install and verify rattler-build. The Conda recipes update build environment values, define a shared libcuvs staging output, and add runtime dependencies to benchmark and package outputs.

Changes: Build and packaging

Layer / File(s)	Summary
Install and verify rattler-build ci/install_rattler_build.sh, ci/build_cpp.sh, ci/build_python.sh	A new script selects the latest stable rattler-build version, installs it, and checks the installed version. Both CI build scripts source the script.
Recipe environments and CPU benchmark requirements conda/recipes/cuvs/recipe.yaml, conda/recipes/cuvs-bench-cpu/recipe.yaml	The recipes forward additional build environment values. The CPU benchmark recipe adds runtime dependencies, including platform-specific dependencies.
Stage shared libcuvs build configuration conda/recipes/libcuvs/recipe.yaml	The recipe moves shared build settings and requirements into libcuvs-build. The headers, library, tests, examples, and ANN benchmark outputs inherit the staging configuration.
Set libcuvs output runtime requirements conda/recipes/libcuvs/recipe.yaml	The libcuvs, tests, examples, and ANN benchmark outputs add runtime dependencies. The ANN benchmark sets RAPIDS_CONDA_ARCH and adds architecture- and platform-specific dependencies.
