test: move WPT to its own testing module

This is first in a hoped-for series of moves away from a monolithic
common.js that is loaded for every test and towards a more modular
approach. (In the end, common.js will hopefully contain checks for
variables leaking into the global space and perhaps some of the more
ubiquitous functions like common.mustCall().)

Move the WPT testing code to its own module.

## Common module API

The common.js module is used by tests for consistency across repeated
tasks. It has a number of helpful functions and properties to help with
writing tests.

### allowGlobals(...whitelist)
* `whitelist` [&lt;Array>](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array) Array of Globals
* return [&lt;Array>](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array)

Takes `whitelist` and concats that with predefined `knownGlobals`.

### arrayStream
A stream to push an array into a REPL

### busyLoop(time)
* `time` [&lt;Number>](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Data_structures#Number_type)

Blocks for `time` amount of time.

### crashOnUnhandledRejection()

Installs a `process.on('unhandledRejection')` handler that crashes the process
after a tick. This is useful for tests that use Promises and need to make sure
no unexpected rejections occur, because currently they result in silent
failures.

### ddCommand(filename, kilobytes)
* return [&lt;Object>](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object)

Platform normalizes the `dd` command
