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.
