[WIP] descriptive_rename: Script for Inclusive Language variable renames

[Saul Wold]

This script searches for a list of variable that have been renamed
and converts them to their more descriptive names. It also searches
for a list of variables that have been removed or deprecated and
prints a message.

It will print a message to inform the user that there are terms that
need to be updated in their files. Many of these changes are context
sensitive and may not be modified as they might be existing calls to
other libraries. This message is informational only.

I have tested this on poky and meta-openembedded so far.
