Fix `closeHandle` bug, add `setFileSize`, make `resize` work on Windows (#21375)
* Add general purpose `setFileSize` (unexported for now). Use to simplify `memfiles.open` as well as make robust (via hard allocation, not merely `ftruncate` address space allocation) on systems with `posix_fallocate`. As part of this, fix a bad `closeHandle` return check bug on Windows and add `MemFile.resize` for Windows now that setFileSize makes that easier. * Adapt existing test to exercise newly portable `MemFile.resize`. * Since Apple has never provided `posix_fallocate`, provide a fallback. This is presently written in terms of `ftruncate`, but it can be improved to use `F_PREALLOCATE` instead, as mentioned in a comment.
