Scan for line length violations in edkrepo

[kevinsun49]

https://peps.python.org/pep-0008/#maximum-line-length

There may be areas in the code where some lines are of a very long length (>120 characters). Propose shortening them by breaking into multiple lines via the following protocol:

• Strong preference to use implicit line continuation inside () [] and {}
• Expressions can be wrapped in ()
• Otherwise, default to using a backslash character \ to indicate line break
