std/fs: `walk` not found error is not `Deno.errors.NotFound`

See original GitHub issue

If you pass a path to walk that does not exist on the fs, the returned promise rejects with an Error, not a Deno.errors.NotFound.

Related https://github.com/denoland/deno_std/issues/1216 which contains steps to reproduce.

After some investigations, I believe it is due to the same underlying issue: Rust std::fs categorise Not a directory (ENOTDIR) error as Other instead of NotFound. That error then get propagated from lstat/stat op in Deno.

Worth noting that a new NotADirectory is available in Rust on nightly right now which will help with the issue.

So although far form ideal, it is expected that Deno.errors.NotFound is not returned from walk.

If I put a file of the same name of walk entrypoint, then I get Error: Not a directory (os error 20), readdir './deno'. This might be the actual problem in the above line in fresh?
