Burak Emir 992d435023 Replace unused bindings with anonymous binding in lower/testdata. (#6479) 
This updates lower/testdata to use _ instead of proper names, in order
to avoid the "unused binding" warnings from #2022 which are being
implemented. These changes do not depend on the implementation which
should make everything easier to review.

See #6460 with part 1 of the implementation. It was split upon request
in order to make reviewing easier, the original state of the PR was
updating hundreds of test cases.
The PR has thus been split, part 2 including test cases changes can be
viewed at
https://github.com/burakemir/carbon-lang/tree/unused_pattern_bindings_p2022_impl_part2
... many tests need to be updated, so it seems best to get those tests
out of the way that are not interesting.

These are not all tests in lower/testdata - a few of them are
interesting in the sense that they cannot use '_' because it leads to
failed redeclaration check. This is exactly the scenario described in
#3763 which requires the 'unused' marker. Those are left untouched here
but are updated in
https://github.com/burakemir/carbon-lang/tree/unused_pattern_bindings_p2022_impl_part2
