Update cppcheck to 2.10 on Ubuntu

[ygoumaz]

Update cppcheck to 2.10 on ubuntu to match versions between platforms. Also, restrict cppcheck to given platforms (instead of all configurations on all platforms, which is redundant).

With this update, we can revert useless empty strings initializations (see #6002 (comment))

Thank you!
Everything seems fine to me.
I'm now checking if the same is also working locally.

I also found some other files where there is default initialization in the initialization list that could be removed.
Can I add them to this PR?

Yes, you can directly push your changes to this PR.

I tested locally but I'm receiving many errors (like the following one):

src/webots/build/debug/WbRobotWindow.moc.cpp:14:0: error: #error "The header file 'WbRobotWindow.hpp' doesn't include <QObject>." [preprocessorErrorDirective]
#error "The header file 'WbRobotWindow.hpp' doesn't include <QObject>."

It seems we should also skip the build folder.
I assume these errors don't occur on the CI because Webots is not compiled and the build folder is empty.

[ygoumaz]

Yes, you are right, the build folder doesn't exist in the CI. I will add the exception on the build folder, as it doesn't make a lot of sense to test those files.

Thank you!

I tested the latest version and I'm still getting some of these errors due to the MOC files for a couple of other folders.
I just commit the changes so that you can review them.

[ygoumaz]

It looks good to me, I let you approve the PR if everything works correctly locally now.
