示例1: _moveDomModuleStyleIntoTemplate
/**
* Old Polymer supported `<style>` tag in `<dom-module>` but outside of
* `<template>`. This is also where the deprecated Polymer CSS import tag
* `<link rel="import" type="css">` would generate inline `<style>`.
* Migrates these `<style>` tags into available `<template>` of the
* `<dom-module>`. Will create a `<template>` container if not present.
*
* TODO(usergenic): Why is this in bundler... shouldn't this be some kind of
* polyup or pre-bundle operation?
