Have auto-generated .py files be created during make

[lbleier-GSFC]

Is your feature request related to a problem? Please describe.
The auto-generated .py files that are created by pyuic5 in order to interface between pyqt5 and the UI are unnecessarily caught in various checks (e.g. lgtm) and git commits. As these are auto-generated, checking them is unnecessary and adds extra complexity to our CM process

Describe the solution you'd like
Keep the .ui files only and use pyuic5 to regenerate the equivalent .py files during the cFS build process.

Additional context
Some end users may not want to use this app, so forcing them to install pyqt5 and related tools is not ideal. Therefore, this should only be done if pyuic5 is actually installed on a user's system and skipped otherwise, with the understanding that the app will be unusable unless built properly.
