suggestion: finalize replacements for `Deno.fdatasync[Sync]()` and `Deno.fsync[Sync]()`

[iuioiua]

The following I/O APIs should be replaced with Deno.FsFile methods. This has partially been done already. However, we haven't been able to finalize the new API names, as indicated in #22085.

1. Deno.fdatasync[Sync]() (currently Deno.FsFile.syncData[Sync]())
2. Deno.fsync[Sync]() (currently Deno.FsFile.sync[Sync])

Are there any plans for stabilizing these (and the file locking) APIs?

This is blocking deno sqlite from upgrading to the new API: https://github.com/dyedgreen/deno-sqlite/pull/259

We're stabilizing these APIs in the next minor release in #23733.
