Add script to update copyright end date

This adds a script to be used to update the copyrights in all
source files so that its end date is '-present' rather than
a specific year.

Also does the following copyright related cleanup:

- Removes the copyright from the docs.

- Removes the Gradle update-copyrights.gradle script that
kept the end date up-to-date (no longer needed w/ end
date set to '-present').

- Updates the copyright in NOTICE.txt to use '-present' end date.

- Removes the unused `src/dist/notice.txt`
