Clean up hostfs TODOs.
This CL does a handful of things: - Support O_DSYNC, O_SYNC - Support O_APPEND and document an unavoidable race condition - Ignore O_DIRECT; we probably don't want to allow applications to set O_DIRECT on the host fd itself. - Leave a TODO for supporting O_NONBLOCK, which is a simple fix once RWF_NOWAIT is supported. - Get rid of caching TODO; force_page_cache is not configurable for host fs in vfs1 or vfs2 after whitelist fs was removed. - For the remaining TODOs, link to more specific bugs. Fixes #1672. PiperOrigin-RevId: 317985269
