Michael Achenbach d08e8691fd [build] Port latest MB from Chromium 
This ports the MB script from Chromium until revision:
https://crrev.com/66958462e684149bcb220000868e8247096e435b

The main difference is the removed gyp support.

This reapplies V8-side changes from:

MB - The Meta-Build wrapper

MB is a simple wrapper intended to provide a uniform interface to either GYP or GN, such that users and bots can call one script and not need to worry about whether a given bot is meant to use GN or GYP.

It supports two main functions:

  1. "gen" - the main gyp_chromium / gn gen invocation that generates the Ninja files needed for the build.

  2. "analyze" - the step that takes a list of modified files and a list of desired targets and reports which targets will need to be rebuilt.

We also use MB as a forcing function to collect all of the different build configurations that we actually support for Chromium builds into one place, in //tools/mb/mb_config.pyl.
