Subject: fix: Deno.readSync on stdin (#6126)

Currently sync operations on stdin are failing because tokio::Stdin
cannot be converted to a std::File.

This commit replaces tokio::stdin with a raw file descriptor
wrapped in a std::fs::File which can be converted to a
tokio::File and back again making the synchronous version
of op_read actually work.
