245 switch to cavl2

[songmeo]

closes #245

[pavel-kirienko]

What #245 was trying to say is that cavl2 should no longer be vendored as part of libcanard itself, but rather it has to be provided by the user. One practical implication is that we need to remove it from the libcanard directory, and place it instead somewhere under lib/cavl2/cavl2.h (should it be a git submodule? probably not), which will then be added as a system include directory. Using a blanket -system for the entire libcanard directory is harmful because it will squelch bona fide warnings from the compiler concerning libcanard's own header.

Direct compiler invocations in the CI script will need to be updated accordingly.

Also, see if you can use CAVL2_TO_OWNER instead of the mutable container macros

This Sonar report is legit, we could address it in this changeset as well since it's minor:

The other one requires a // NOSONAR comment.

Please address the remaining minor issues and then merge.

Redundant; we already have include_directories(${library_dir}) on line 71
