[RFC PATCH] perf scripts python: Add support for input args in gecko script

[Anup Sharma <anupnewsmail@gmail.com>]

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.

Hi Arnaldo,
Thanks for providing such a detail insights here:

https://lore.kernel.org/linux-perf-users/ZMJaDGhSnhIlK3Nd@kernel.org/

I've successfully confirmed that the command "perf script gecko -a sleep 1"
is functioning as expected. However, I encountered an issue when attempting
to provide arguments such as "--user-color" and "--save-only" to the
"gecko.py" script while using the "perf script gecko" or "perf script report
gecko" commands.

In order to understand the inner workings of how these commands are executed,
I delved into the "buildin-script.c" code. From my investigation, it seems
that the arguments are taken into account for the "record" functionality,
rather than for "report."

To address this  I added this changes.

I've also documented the usage of this command in our wiki:
https://perf.wiki.kernel.org/index.php/Tutorial#Firefox_Profiler

For most cases where users do not require specific "gecko.py" arguments, the
command "perf script gecko -a sleep 0.5" is sufficient. However, if users
intend to provide particular arguments to "gecko.py," they should employ the
command "perf script report gecko --save-only=cloud_cpu.json."

I believe there might be an intelligent solution to streamline this process.
Therefore, I would greatly appreciate your insights on this matter.
