[RFC] Keeping v1.x branch in sync with master branch w.r.t. license and legal changes

[mseth10]

Problem statement

In the past few months, several PRs related to license and legal changes have been merged to master branch. Not all of these changes were back-ported to v1.x branch. There is an effort required to keep v1.x branch updated with these changes and in sync with the master branch.

Proposed solutions

Towards this effort, I scanned through some license related files (LICENSE, NOTICE, rat-excludes, license/* and tools/license_header.py) and made sure that they are up-to-date with changes in master branch. In doing so, I identified the following PRs in master branch made in past 3 months:

• Fix test_rat_check #19711
• [LICENSE] Reorganize rat-excludes file to ease license auditing #19743
• Update LICENSE #19478
• fix license for blockingconcurrentqueue #19909
• [NOTICE] update notice year #19813

with corresponding PRs in v1.x branch (created ones that were missing):

• [v1.x] Backport [LICENSE] Reorganize rat-excludes file to ease license auditing (#19743) #19799
• [1.x] Update LICENSE #19704
• [v1.x] add missing license fix from master to v1.x #19916
• [v1.x] fix license for blockingconcurrentqueue #19910
• [v1.x] update notice year #19893

With these PRs, all the above mentioned files are updated in v1.x branch and are in sync with master branch.

Creating this RFC to get inputs from community on what other license related files to look into and if there is any other license related PRs that is missed here. Thanks!
