Since we do not actually use the Console constructor to
instantiate the global console, move the two piece of
code into two different JS files for clarity, and make
console.js a mere re-export of the global console.
The hope is to make the global console, a namespace, more
web-compatible while keeping the Console constructor
available for backwards compatibility.

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.

In 62232361 we made the console.Console function construct an object
with methods from Console.prototype bound to the instance, instead of
with methods found on the prototype chain to be bound on the instances,
thus breaking users overriding these methods when subclassing Console
because they are not expecting this function to construct a
namespace whose methods are not looked up from the prototype
chain.
This patch restores the previous behavior since it does not affect
the characteristics of the global console anyway. So after this patch,
the Console function still constructs normal objects with function
properties looked up from the prototype chain but bound to the
instances always.

From the WHATWG console spec:
> For historical web-compatibility reasons, the namespace object for
> console must have as its [[Prototype]] an empty object, created as
> if by ObjectCreate(%ObjectPrototype%), instead of %ObjectPrototype%.
Since in Node.js, the Console constructor has been exposed through
require('console'), we need to keep the Console constructor but
we cannot actually use `new Console` to construct the global console.
This patch changes the prototype chain of the global console object,
so the console.Console.prototype is not in the global console prototype
chain anymore.
```
const proto = Object.getPrototypeOf(global.console);
// Before this patch
proto.constructor === global.console.Console
// After this patch
proto.constructor === Object
```
But, we still maintain that
```
global.console instanceof global.console.Console
```
through a custom Symbol.hasInstance function of Console that tests
for a special symbol kIsConsole for backwards compatibility.
This fixes a case in the console Web Platform Test that we commented
out.

It also fixes a edge case with `maxArrayLength` and the map.entries()
iterator. Now the whole entry will be visible instead of only the key
but not the value of the first entry.
Besides that it uses a slighly better algorithm that improves the

Node.js exposes `console.group()` and `console.groupEnd()` via the
inspector. These functions have no apparent effect when called from
Node.js without the inspector. We cannot easily hide them when Node.js
is started without the inspector because we support opening the
inspector during runtime via `inspector.port()`.
Implement a minimal `console.group()`/`console.groupEnd()`. More
sophisticated implementations are possible, but they can be done in
userland and/or features can be added to this at a later time.
`console.groupCollapsed()` is implemented as an alias for
`console.group()`.
