meson: Add an option to build examples
Required renaming threadshare/benchmark to threadshare/ts-benchmark because 'benchmark' as a target name is reserved for meson's `benchmark` target. Disabled by default because cargo decides that it has to rebuild everything, and is really slow because of that. Also required adding --features for setting features required by the examples. Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs/-/merge_requests/1028>
