This patch: - Refactors the Console constructor: moves the property binding code into and the writable streams binding code into two methods defined on the Console.prototype with symbols. - Refactors the global console creation: we only need to share the property binding code from the Console constructor. To bind the streams we can lazy load `process.stdio` and `process.stderr` so that we don't create these streams when they are not used. This significantly reduces the number of modules loaded during bootstrap. Also, by calling the refactored-out method directly we can skip the unnecessary typechecks when creating the global console and there is no need to create a temporary Console anymore. - Refactors the error handler creation and the `write` method: use a `kUseStdout` symbol to tell the internals which stream should be loaded from the console instance. Also put the `write` method on the Console prototype so it just loads other properties directly off the console instance which simplifies the call sites. Also leaves a few TODOs for further refactoring of the console bootstrap. PR-URL: https://github.com/nodejs/node/pull/24534 Reviewed-By: Gus Caplan <me@gus.host>
