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.
