Ben Clayton 5b36d2c612 Remove all unnecessary includes
All includes from .cc to .h are preserved, even when transitively included.

It's clear that there are far too many includes in header files, and we should be more aggressive with forward declarations. tint:532 will continue to track this work.

There are, however, plenty of includes that have accumulated over time which are no longer required directly or transitively, so this change starts with a clean slate of *required* includes.
