feat: Add `Deno.exitCode` API (#23609) This commits adds the ability to set a would-be exit code for the Deno process without forcing an immediate exit, through the new `Deno.exitCode` API. - Implements `Deno.exitCode` getter and setter: Adds support for setting and retrieving a would-be exit code via `Deno.exitCode`. This allows for asynchronous cleanup before process termination without immediately exiting. - Ensures type safety: The setter for `Deno.exitCode` validates that the provided value is a number, throwing a TypeError if not, to ensure that only valid exit codes are set.
