Rollup merge of #90955 - JohnTitor:os-error-123-as-invalid-input, r=m-ou-se

Rename `FilenameTooLong` to `InvalidFilename` and also use it for Windows' `ERROR_INVALID_NAME`

Address https://github.com/rust-lang/rust/issues/90940#issuecomment-970157931
`ERROR_INVALID_NAME` (i.e. "The filename, directory name, or volume label syntax is incorrect") happens if we pass an invalid filename, directory name, or label syntax, so mapping as `InvalidInput` is reasonable to me.
