MINOR: Add verify_license tool (#18931)
This patch adds the verify_license.py tool. It compares the libraries shipped within the tarball to the LICENSE file, and vice versa, to ensure that they are aligned. It also slightly update the format of the LICENSE file to make it easier to parse it. Reviewers: Chia-Ping Tsai <chia7712@gmail.com>, Mickael Maison <mickael.maison@gmail.com>
