This commit adds accessors for more fields in `fs::Metadata` on Windows which weren't previously exposed. There's two sources of `fs::Metadata` on Windows currently, one from `DirEntry` and one from a file itself. These two sources of information don't actually have the same set of fields exposed in their stat information, however. To handle this the platform-specific accessors of Windows-specific information all return `Option` to return `None` in the case a metadata comes from a `DirEntry`, but they're guaranteed to return `Some` if it comes from a file itself. This is motivated by some changes in CraneStation/wasi-common#42, and I'm curious how others feel about this platform-specific functionality!

@marmistrz I generally personally prefer to keep the original structures around for as long as possible, but the recent addition of UWP made that untenable anyway, so I went ahead and did what you're thinking anyway @bors: r=sfackler |
