* 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.

Bumps `rules_foreign_cc` to v0.10.1 (October 2023), `bazel_skylib` to
v1.5.0 (November 2023), `rules_python` to v0.27.1 (December 2023).
Also syncs GoogleTest to v1.12.1 (the last C++11 supporting version) to
be the same as in MODULE.bazel.
Since the latest `rules_python` changed its setup calling convention,
that is updated also in the WORKSPACE file.
* 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.
* Change nanobind linkage to response file approach
This change needs https://github.com/bazelbuild/bazel/pull/18952 to be
merged first. Fixes macOS linkage of GBM's nanobind bindings on macOS by
supplying a linker response file instead of `-undefined dynamic_lookup`.
The latter has since been deprecated on macOS.
* Fix bazel_skylib checksum, bump skylib version in MODULE.bazel
* Bump Bazel to version 6.4.0 for linker response file support
* Migrate to bzlmod
* Update Python version to PY3, as indicated by the actual source file.
* Migrate more libraries & first draft of direct pywheel rule usage in Bazel
* Integrate with nanobind and libpfm
* Make Python toolchain a dev dependency
* Undo py_wheel usage until later
* Added support for bzlmod for C++ parts of google_benchmark.
* Make //tools:all buildable with --enable_bzlmod
