Add workflows to replace Codacy

[alanking]

Codacy runs a number of different linters across various languages used in our repositories. We should add workflows that run some of these linters (or replace them) so that we do not need to rely on Codacy anymore.

Some of the linters being run for consideration here:

C/C++:

• cppcheck (https://cppcheck.sourceforge.io/)
• Flawfinder (https://dwheeler.com/flawfinder/)

Python:

• Prospector (https://prospector.landscape.io/en/master/) (combines several tools: Pyflake, pycodestyle, McCabe, and more)
• Bandit (https://bandit.readthedocs.io/en/latest/)

The list above is just a sampling of what I've seen in our Codacy issues and is by no means exhaustive nor is it a list of recommended tools.
