perf script: Add -e option to flamegraph script
When processing the perf data file generated with multiple events,
the flamegraph script will count all the events regardless of
different event names.
This patch tries to add a -e option to specify the event name that
the flamegraph will be generated accordingly. If the -e option omitted,
the behavior remains unchanged.

Make vmlinux detection automatic and use Perf's default objdump
when -d is specified. This will make it easier for a test to use the

perf scripts python gecko: Launch the profiler UI on the default browser with the appropriate URL
All required libraries have been imported and make sure that none of
them are external dependencies.
perf scripts python gecko: Launch the profiler UI on the default browser with the appropriate URL
All required libraries have been imported and make sure that none of
them are external dependencies. To achieve this, created a virt env and
verified.
Modified usage information and added combined command.
Modified the main() function to read the --save-only command-line option
and set the output_file variable accordingly.
Modified the trace_end() function to check for the output_file variable.
If it is set, the profiler data is saved to a local file in Gecko
Profile format, or the profiler.firefox.com is opened on the default
browser.
Included trace_begin() to initialize the Firefox Profiler and launch the
default browser to display the profiler.firefox.com.
Added a new function launchFirefox() to start a local server and launch
the profiler UI on the default browser with the appropriate URL.
Created the "CORSRequestHandler" class to enable Cross-Origin Resource
Sharing.
Summary:
This integration now includes a exiting feature to conveniently host the
Gecko Profile data on a local server and open it directly in the default
web browser.
This means that users can now effortlessly visualize and analyze the
profiler results with just a single click.
The addition of the --save-only command-line option allows users to save
the profiler output to a local file in Gecko Profile format, but the
real highlight lies in the capability to seamlessly launch a local
server, making the data accessible to Firefox Profiler via a web
browser.
In addition, it's important to highlight that all data are hosted
locally, eliminating any concerns about data privacy rules and
regulations.
