[m4] conan v2

[jellespijker]

Specify library name and version: m4/x.x.x

I thook the liberty of defining a conf value: tools.m4:bin which is the path to the binary m4 executable. I don't know if tools is a reserved namespace but it maid sense in my mind. Let me know if that should change.

^{Note: To save resources, CI tries to finish as soon as an error is found. For this reason you might find that not all the references have been launched or not all the configurations for a given reference. Also, take into account that we cannot guarantee the order of execution as it depends on CI workload and workers availability.}
