types: Add type annotations to jitlist_bisect.py

Summary:
Added type annotations to all functions in jitlist_bisect.py that were
missing them: `write_jitlist`, `read_jitlist`, `get_compiled_funcs`,
`run_bisect`, `parse_args`, and `main`. This improves code readability
and enables better static analysis.
