Auto merge of #57108 - Mark-Simulacrum:license-remove, r=pietroalbini

Remove header licenses across the project

This pull request removes the header licenses from files across the Rust repository.

I've attempted to check for any remaining headers and removed all of them -- any we've missed can be removed in the future; there's nothing blocking that.

Unfortunately, not all of the changes are as basic as "removing a header" because some of them required test file updates or otherwise. However, I am fairly confident that the changes in this pull request, while wide-sweeping, are unlikely to actually make any tests fail to properly test the code; any non-script based changes were manual and carefully verified.
