Add pre-commit hook with code formatting

Add pre-commit hook with code formatter under the hood

In the context of PR, trying to solve an issue related to file formatting during pre-commit hook.

Description

The issue #30145 outlines the backward of the previous approach and why it was reverted. Based on that, wanna suggest some improvements:

1. Working with the files only in staged/unstaged areas.
2. Resolving the issue with partially committed files.
3. Setting up the hook inside both build.ps1 and build.sh - Might need help with setting the hook up correctly

Fixes #27632

Thanks for the change! Looks like the original blocking issue has been fixed, and this does solve the build.sh problem - @SteveSandersonMS, any concerns with this approach?
