perf scripts python: Add support for input args in gecko script

Refines the argument handling mechanism in the "gecko-report" script to
enable better compatibility and improved user experience.

The script now differentiates between scenarios where arguments are
provided for record and report cases where gecko.py arguments are
passed.
