CVE-2024-27931: Insufficient permission checking in `Deno.makeTemp*` APIs

Insufficient validation of parameters in Deno.makeTemp* APIs would allow for creation of files outside of the allowed directories. This may allow the user to overwrite important files on the system that may affect other systems.

A user may provide a prefix or suffix to a Deno.makeTemp* API containing path traversal characters. The permission check would prompt for the base directory of the API, but the final file that was created would be outside of this directory:

$ mkdir /tmp/good
$ mkdir /tmp/bad
$ deno repl --allow-write=/tmp/good
> Deno.makeTempFileSync({ dir: "/tmp/bad" })
┌ ⚠️  Deno requests write access to "/tmp/bad".
├ Requested by `Deno.makeTempFile()` API.
├ Run again with --allow-write to bypass this prompt.
└ Allow? [y/n/A] (y = yes, allow; n = no, deny; A = allow all write permissions) > n
❌ Denied write access to "/tmp/bad".
Uncaught PermissionDenied: Requires write access to "/tmp/bad", run again with the --allow-write flag
