* Add a bzlmod Python bindings build
Uses the newly started `@nanobind_bazel` project to build nanobind
extensions. This means that we can drop all in-tree custom build defs
and build files for nanobind and the C++ Python headers.
Additionally, the temporary WORKSPACE overwrite hack naturally goes away
due to the WORKSPACE system being obsolete.
* Bump ruff -> v0.3.1, change ruff settings
The latest minor releases incurred some formatting and configuration
changes, this commit rolls them out.

Also fix a mypy error in `tools.gbench.util` - the condition behaves the
same as before, but in the new mypy version, the old condition results
in an unreachable code error for the final `return False` statement.
This is most likely a bug in mypy's reachability analysis, but the fix
is easy enough here to circumvent it.
* Run `pre-commit autoupdate`, fix stale pyproject.toml comments
* Set `--enable_bzlmod=false` for the moment
Until the newer nanobind tags are pushed to the BCR, it's best to disable
bzlmod for the bindings, because the Python CI breaks due to Bazel 7
enabling bzlmod by default.
* Remove E203 ignore, add linebreaks to semantically group ruff options
Saves one pre-commit hook, some pyproject.toml configuration,
and provides much better performance with almost identical behavior.

This behaves the same, and saves a pre-commit step. ruff just needs an
additional package location hint to correctly map first-part packages
(in this case, `google_benchmark`).
This revealed a misformat in the `google_benchmark.__init__`, which is
now fixed.
* Add pre-commit config and GitHub Actions job
Contains the following hooks:
* buildifier - for formatting and linting Bazel files.
* mypy, ruff, isort, black - for Python typechecking, import hygiene,
static analysis, and formatting.
The pylint CI job was changed to be a pre-commit CI job, where pre-commit
is bootstrapped via Python.
Pylint is currently no longer part of the
code checks, but can be re-added if requested. The reason to drop was
that it does not play nicely with pre-commit, and lots of its
functionality and responsibilities are actually covered in ruff.
* Add dev extra to pyproject.toml for development installs
* Clarify that pre-commit contains only Python and Bazel hooks
* Add one-line docstrings to Bazel modules
* Apply buildifier pre-commit fixes to Bazel files
* Apply pre-commit fixes to Python files
* Supply --profile=black to isort to prevent conflicts
* Fix nanobind build file formatting
* Add tooling configs to `pyproject.toml`
In particular, set line length 80 for all Python files.
* Reformat all Python files to line length 80, fix return type annotations
Also ignores the `tools/compare.py` and `tools/gbench/report.py` files
for mypy, since they emit a barrage of errors which we can deal with
later. The errors are mostly related to dynamic classmethod definition.
