[twig:compile] Compile all twig template files

[itsdarrylnorris]

Problem / Motivation

Some sites want to compile Twig (and container) on staging and deploy to production with production being readonly PHP wise. We need a twig compiler for them.

This is the same functionality as drush twig-compile in Drush.

There is some plan on adding this functionality into core, however, this is been postpone. https://www.drupal.org/node/2308215

Solution

We need a command that compiles all twig templates.
