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.

37571bc32d ProgramBuilder: Swap parameter order for Var and Const
Move the storage parameter after type.
Const() has no use for storage classes, so this parameter will be removed in the next change.
This reordering keeps Var() and Const() parameter types identical for the first two non-optional fields
