console: lazy load process.stderr and process.stdout
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.

f895b5a58e src: cache the result of GetOptions() in JS land
Instead of calling into C++ each time we need to check the value
of a command line option, cache the option map in a new
`internal/options` module for faster access to the values in JS land.

util: move inspect in separate file
The inspect function became very big and it's better to handle this
in a separate file.

Instead of having a custom, static, hand-written string

generate it in JS when requested.
