Fix license and notice issue

[luoyuxia]

Purpose

Linked issue: close #2697

• LICENSE should be a bit updated. For instance, mvnw is not part/used in
  the code of the distribution.

• The licenses folder contains some confusing
  files (for instance LICENSE-re2j and LICENSE.re2j, which one is relevant,
  LICENSE.cddlv1.1 applies to which dependency ?, ...)

• The NOTICE is not
  fully correct: the NOTICE should include the NOTICE for Apache
  dependencies. The list of BSD licensed dependencies (like jsch, paranamer,
  ...) should not be in the NOTICE, it should be in LICENSE.

Brief change log

1: remove mvnw from binary release
2: unify LICENSE-re2j and LICENSE.re2j
3: add a LICENSE file to list BSD(Non-Apache) licensed dependencies, remove the listed from NOTICE
After go through https://infra.apache.org/licensing-howto.html#permissive-deps, seem it recommand to keep NOTICE as simple as possible.

Pull request overview

Updates Fluss’ release/legal artifacts to address ASF licensing/notice compliance (issue #2697), including generating binary distribution LICENSE/NOTICE variants and moving non-Apache dependency listings out of NOTICE into LICENSE files.

Changes:

• Add release helper scripts to derive binary LICENSE/NOTICE by removing the Maven Wrapper section.
• Update create_binary_release.sh to emit derived LICENSE/NOTICE into the binary tarball.
• Refresh multiple module META-INF/NOTICE files to remove non-Apache dependency listings, and introduce corresponding META-INF/LICENSE (+ license texts under META-INF/licenses/) for bundled third-party components.
