[Parent issue] Create and add CODEOWNERS linter baseline files

[JimSuplizio]

Before creating and enabling the CodeownersLinter pipelines, every repository that this will be enabled for needs to have a baseline file created and checked in. The baseline file will be used to filter errors, allowing the pipeline run and pass in spite of existing errors. This will allow the pipeline to be enabled for CODEOWNERS changes and only report or block a check in if someone is adding brand new errors to a CODEOWNERS files. AKA, it'll allow the existing errors, at least until the baseline errors are fixed, and prevent new errors for being added.

The repositories that require baseline files are
azure-sdk
azure-sdk-tools
azure-sdk-for-android
azure-sdk-for-c
azure-sdk-for-cpp
azure-sdk-for-go
azure-sdk-for-ios
azure-sdk-for-java
azure-sdk-for-js
azure-sdk-for-net
azure-sdk-for-python

Closing this out, all of the repositories now have their CODEOWNERS linter error baseline files and linter pipelines created and enabled.
