Port to TinySPARQL header/dependency, and use wrap file to include it
Drop our special -Dtracker_core option, and handle TinySPARQL being built as a subproject transparently, handled by Meson. This will only happen if the dependency is not found, or it does not meet the required version.
In order to do this, the project had to be updated to using the tinysparql-3.0 dependency, and the new recommended header file as well.
