Revert "Remove ament macros"

[ChrisThrasher]

This reverts commit 7cb590a.

Here I come back tucking my tail between my legs. We wrote install interface tests and even did some manual testing with this new RSL version in the wild using projects that depend on RSL. We found no issues so we felt comfortable shipping. Alas something about the Debian packaging of RSL results in an rsl::rsl target which seemingly lacks the correct interface install directories or interface link libraries resulting in numerous build failures.

We're unsure why this is the case or why any of this is happening or whether adding ament back will even fix anything.

We might have found a fix. Switching to consuming RSL via target_link_libraries appears to fix this issue.

We decided to stick with our ament-free solution so no need to revert anything!

It's not a bug; it's a feature!
