Rollup merge of #127750 - ChrisDenton:safe-unsafe-unsafe, r=workingjubilee

Make os/windows and pal/windows default to `#![deny(unsafe_op_in_unsafe_fn)]`

This is to prevent regressions in modules that currently pass. I did also fix up a few trivial places where the module contained only one or two simple wrappers. In more complex cases we should try to ensure the `unsafe` blocks are appropriately scoped and have any appropriate safety comments.

This does not fix the windows bits of #127747 but it should help prevent regressions until that is done and also make it more obvious specifically which modules need attention.
