Subject: feat: `Deno.FsFile.dataSync()` and `Deno.FsFile.dataSyncSync()`
 (#22019)

This change:
1. Implements `Deno.FsFile.dataSync()` and `Deno.FsFile.dataSyncSync()`.
2. Deprecates `Deno.fdatasync()` and `Deno.fdatasyncSync()` for removal
in Deno v2, in favour of the above corresponding methods.
3. Replaces use of `Deno.fdatasync()` and `Deno.fdatasyncSync()` with
the above instance methods.
