Finish clang-tidy cleanups (#3003)

* Add .clang-tidy configuration.
* A separate .clang-tidy is used for hal includes to suppress modernize-use-using
  (as these are C headers).
* Add NOLINT where necessary for a clean run.
* Add clang-tidy job to lint-format workflow.  This workflow is now only run on PRs.
  To reduce runtime, clang-tidy is only run on files changed in the PR.

Two wpilibc changes; both are unlikely to break user code:
* BuiltInAccelerometer: Make SetRange() final
* Counter: Make SetMaxPeriod() final

After these cleanups, the only file that does not run cleanly is
cscore_raw_cv.h due to it not being standalone.

cscore/src/main/native/cpp/jni/CameraServerJNI.cpp
