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
