Scripts under `tools/` should probably be modified to import a common module.

[echo-lalia]

A lot of the scripts under tools/ are re-implementing the same code. This means that when updates are made, the exact same modification needs to be made in several different locations.

Currently, some scripts are import the NON_DEVICE_FILES constant from the parse_files script, but this still feels a little inelegant.

It would make a lot more sense if there was some kind of common build utility module that hosted the logic for things like extracting device files, getting device names, getting default paths, etc.
