Add copyright tools and templates to bin/tools/

[nab880]

Added a simple automated script to update the copyright information
Needs to be ran from the base directory

python bin/tools/update_copyright.py

By default the script updates the cpp, makefile, and markdown copyrights based on their repsective .txt files in bin/tools.
Since the Copyright is already updated to 2025, I haven't ran the script to update the copyright.
There are some slight variations in how some of the existing copyright is formatted so there will naturally be some changes when it is used to update the copyright.
