Feature Request: Display what architectures ROS packages support

[icolwell-as]

I think it would be super handy to have a list of what CPU architectures a given package supports.
Maybe listing supported archs in the "Package Summary" section on the package page would be best.

Unless I'm missing something, the best way I currently get this information is by searching the apt sources.

One way to find this information is through the packaging status pages for a given distribution:

• Noetic amd64: http://repositories.ros.org/status_page/ros_noetic_default.html
• Noetic arm64: http://repositories.ros.org/status_page/ros_noetic_ufv8.html
• Noetic armhf: http://repositories.ros.org/status_page/ros_noetic_ufhf.html
