Engine benchmarks download tool is able to plot multiple branches

[Akirathan]

Pull Request Description

Engine benchmark downloader tool bench_download.py can now plot multiple branches in the same charts. The tooltips on the charts, displayed when you hover over some data point, are now broken for some branches. I have no idea why, it might be a technical limitation of the Google charts library. Nevertheless, I have also extended the selection info section, that is displayed under every chart, where one can see all the important information, once you click on some data point.

Options added:

• --branches specifies list of branches for which all the benchmark data points will be in the plots. The default is develop only.
• --labels that can limit the number of generated charts.

This PR also deprecates the --compare option. There is no reason to keep that option around since we can now plot all the branches in the same charts.

An example for plotting benchmarks for PR #7009 with

python bench_download.py -v --since 2023-07-01 --until 2023-07-11 --branches develop wip/jtulach/ArgumentConversion

is:

Important Notes
