Windows 10 1607+ has the feature to delete files with "POSIX semantics".

See the documentation on FILE_DISPOSITION_POSIX_SEMANTICS. This should be possible to do from user mode via NtSetInformationFile.

For the implementation of __wasi_path_unlink_file, I think we should probably attempt to unlink the file with POSIX semantics first and fallback to stdlib's remove_file implementation if it's not supported.

See #566 for some context to this feature.

When implemented, we should enable the dangling_fd test to cover this when the operating system is Windows 10 1607 or higher.

Closing this because WASI is not tracked in this repo anymore.
