There was an unneeded call to `device_uvector::release()` that did not use the return value. rapidsai/rmm#857 marks that function `[[nodiscard]]`, so removing this allows libcudf to compile after the RMM PR is merged. The `release()` is unnecessary because `prev_base_offsets` is passed by rvalue reference and therefore will be freed when the function exits (the uvector in the calling context it has been moved-from).

#857 introduced a few naming issues in debug builds due to parameter name changes. I rebuilt both C++ and Cython-generated code in debug mode and ran tests, both build and tests succeed now.

Adds a .clang-tidy configuration file. This does not add CI tests yet, but I wanted to get it ready to do so without forcing it on anyone. As-is, this PR will enable clang-tidy "yellow squiggles" if you use clangd in vscode.
Starting with these Checks:
Here is a list of warnings fixed
NOLINT lines have been added where fixes are unavailable, such as with necessary pointer arithmetic or
reinterpret_castcalls.I have a private branch of google test which adds NOLINT lines to suppress warnings caused by gtest's code. I plan to make a PR for this.
There are still a couple of outstanding warnings having to do with "easily swappable parameters" (e.g. when a function takes two sizes. Fixing these requires breaking API changes. Alternatively we could suppress them.)
