Rollup merge of #108306 - klensy:compiletest-up, r=wesleywiser

compiletest: up deps

update `miow` 0.3.7 -> 0.5.0 (which moved from `winapi` to `windows-rs`, [changelog](https://github.com/yoshuawuyts/miow/blob/master/CHANGELOG.md#v050---2022-11-10))
replace `lazy_static` with `once_cell` (there is slow transition to the second crate, in hope of eventually stable stdlib version, yes?)
