Plugins should be selectively tested on OS & archs according to what they support

[Phault]

Currently hyperfine is not tested in CI due to lack of aarch64 builds for macOS. Similarly some tools e.g. https://github.com/Bearer/bearer does not support some OS's.

Nevertheless, they should be still be tested on the platforms they do support.

I imagine the .prototools should be dynamically created for each runner, according to some metadata stored for each plugin.
