Major changes:
* Remove mutable reference section from Blink guide due to recent
Google style changes.
Minor changes:
* Remove Blink guide section on documentation since the Google style
guide already mandates this.
* Add section on TODO formatting to Dos-And-Don'ts page; remove
similar section from Blink guide in hopes the Google guidelines +
Dos-And-Dont's text covers it.
* Add information about C++17 (lack of) support.
Trivial changes:
* Clarify that the Blink style guide is a diff atop the Chromium
guide (which is a diff atop the Google guide).
* Cite Chromium guidance around bare "new" from Blink guide.
* Minor link fixes, wording changes, inlining.
