enforce cmake-format and cmake-lint, other small packaging changes

[jameslamb]

Contributes to rapidsai/build-planning#136

Proposes using cmake-format and cmake-lint here to standardize CMake code style, similar to the way that other RAPIDS libraries do.

The new files cpp/scripts/run-cmake-format.sh and cpp/cmake/config.json were borrowed and then lightly adapted from cuDF (code link).

All changes in CMakeLists.txt and .cmake files here were made automatically by cmake-format, like this:

FORMAT_FILE_URL="https://raw.githubusercontent.com/rapidsai/rapids-cmake/branch-25.02/cmake-format-rapids-cmake.json"
export RAPIDS_CMAKE_FORMAT_FILE=/tmp/rapids_cmake_ci/cmake-formats-rapids-cmake.json
mkdir -p $(dirname ${RAPIDS_CMAKE_FORMAT_FILE})
wget -O ${RAPIDS_CMAKE_FORMAT_FILE} ${FORMAT_FILE_URL}

Notes for Reviewers

How I tested this

git fetch upstream --tags
./ci/release/update-version.sh '0.43.00'
git grep -E '25\.2'
git grep -E '25\.02'
git grep -E '0\.42'

/ok to test

closing this, as the only substantive change it had was related to CMake formatting, and we're going to pursue a better long-term approach than what this PR had been proposing: rapidsai/cugraph#4889 (comment)

Sorry for the noise.
