tools/syz-reporter: add new columns for syz-bisect output

Add new columns to be filled with information from syz-bisect:

Causing Commits
Commit or list of commits that were identified by syz-bisect
being possible culprits for the crash

Fixing Commits
Commit or list of commits that were identified by syz-bisect
being possible fixes for the crash.

Causing Configs
Config options that were identified being dependencies for reproducing
the crash.
