Burak EmirandDana Jansens fec6ce2f9f Implement "unused pattern bindings" p2022 - parsing (#6460) ...

This implements proposal #2022, with changes from #3763 and leads
answers on #6448

Detection of unusedness is happening in
~~`toolchain/check/dataflow_analysis.cpp`~~ next PR. See
[here](https://github.com/burakemir/carbon-lang/tree/unused_pattern_bindings_p2022_impl_part2)
for preview.

~~All test cases with unused bindings were updated in order to avoid
polluting test output.~~
