Resolves: #4565

Update to newer version of clang-format.

The previous clang-format version 8 does not compile on arm64 mac. There is limited support for clang-format binaries before version 10.

This is a gateway toward greatly simplifying the support for pre-commit checking using the python pre-commit infrastructure. See: #5013

FYI: Github actions is having issues: actions/runner#3611

Local macos builds occur properly (my main development environment).

The end goal is to have precommit manage the clang format version, and remove our code with build and manages the clang format version?

@blowekamp Yes! The pre-commit version is much easier to manage and covers a wider range of platforms. Using pre-commit will remove much of the complicated cmake code.

I made this PR as a stepping stone to decouple the pre-commit considerations from updating the clang-format version.

ENH: update clang-format binaries to 19.1.4
26b683a 
Step 1: Download pypi wheels from https://pypi.org/project/clang-format/#files
for each of the platforms.

Step 2: For each wheel:
```bash
if [ $(uname) == "Darwin" ]; then
  xattr -d com.apple.quarantine ${downloaded_wheel_file}
fi
unzip ${downloaded_wheel_file}
cd clang_format/data/bin
tar -cf clang_format.tar clang-format
```

Step 3: Upload the clang_format.tar file to https://data.kitware.com/
Copy the sha512 for the uploaded tarball and change the
has in Utilities/ClangFormat/DownloadClangFormat.cmake

Step 4: Update the allowed version limits
```cmake
set(CLANG_FORMAT_MIN_VERSION 19.1.4)  # First acceptable version
set(CLANG_FORMAT_MAX_VERSION 20.0)  # First unacceptable version
```

Update .clang-format and Example/.clang-format propogating

STYLE: Rigorous style conformance with clang-format 19.1.4
9bd6b75 
The newer version of clang-format has a more rigorous
enforcement of the ITK style.

Most changes include placing the return value of a function
on it's own line, and moving single line function definitions
to the ITK multi-line format (even in macros).

@dzenanz @blowekamp I have addressed all the issues that you pointed out earlier. I found a setting that minimized the differences with clang version 8 with ~130 fewer changed files.

I'd love to get this PR to make progress toward acceptance because it is a key roadblock for evaluating the next set of build improvements (aka pre-commit).

Thank you for moving to a much needed newer version of clang-formatting. It is good to separate the stye preferences from version changes as best we can. Additionally, separating the code formatting changes from the introduction of pre-commit usage is good. Thank you for moving this forwards.

Interestingly, here it goes the other way (compared to the case of the m_LastPipelineMTime = 0; statement). I like having the return m_Pointer; statement on its own line. 👍

@hjmjohnson Thanks, really great! I'm very glad to see such a major clang-format upgrade!

I'm now going to try your PR locally. Don't know if it's necessary to wait until it works on my Windows laptop...

@hjmjohnson Dummy question: I just pulled the master branch and reran CMake. An attempt to commit locally tells me:

clang-format version 19.1.4 is required
Set the path the clang-format 19.1.4 executable with
  git config clangFormat.binary /path/to/clang-format

What should I do? I don't see the clang-format 19.1.4 executable on my disk. My "Bin\ITK\ClangFormat-prefix\src\ClangFormat" still has an old clang-format.exe

@N-Dekker From this commit 0b1fabd it can be deduced to get Windows binary from this link.
