Description

This enables a workaround for the copywrite tooling that lets us correctly automate license compliance in subdirectories that utilize MPL. New copywrite configuration files are added to the impacted subdirs, and the copywrite make target is expanded so that the tool is run locally in those subdirs preceded by a script that removes incorrect license headers (the copywrite tool is currently unable to do this on its own, and this is a workaround until it can be improved).

Testing & Reproduction steps

The new build target can be run locally - all results of a local run as of the time of this change are included as the header updates in this PR.

PR Checklist

• updated test coverage
• external facing docs updated
• appropriate backport labels added
• not a security concern
