[tests] config-dependent cost tests

Summary:
Move where the cost tests are wired into the main Makefile depending on
whether clang/Java/ObjC are supported.

This isn't used as part of `make test`, these are convenience targets to select cost tests. I often use `make show-targets | grep something | xargs make -j 4` and having non-buildable targets there (in my case objc ones) doesn't work.
