Subject: feat: `FsFile.sync()` and `FsFile.syncSync()` (#22017)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This change:
1. Implements `Deno.FsFile.sync()` and `Deno.FsFile.syncSync()`.
2. Deprecates `Deno.fsync()` and `Deno.fsyncSync()` for removal in Deno
v2, in favour of the above corresponding methods.
