m4: add package_type attribute

[jcar87]

Specify library name and version: m4/all

In Conan 2, this is required for downstream consumers to be exposed to PATH/m4 variables from this recipe, when m4 is a transitive dependency (i.e., not direct).

I detected other pull requests that are modifying m4/all recipe:

I'm wondering: what should be the package_type if a recipe is both an application and a library?

I'm wondering: what should be the package_type if a recipe is both an application and a library?

the package_types influence which traits are enabled by default on the consumers side, without consumers having to do so explicitly, but I believe for more special cases consumers do have the freedom of specifying the traits more explicitly to match how something is used

Seems like this is a subset of the linked PR which also seems to add v2 support (Although its v2 pipeline is failing just as this one is) and Chris wants to talk about it at the next shepherds meeting

[prince-chrismc]

The v2 image is so out of date I just ask contributors to ignore that 🙃

The PRs are completely theoretical at this time.

[prince-chrismc]

As for the other PR, Recipes doing things we can not test and what should be allowed has never been resolved so it would be great to have a list of DOs and DONTs to help Give reviewers a base line.

Or at least set a process for the team to decide on them. Then write the list as we go

Being from source should also be a client feature with a conf setting ;) so we can accept that in the future
