Split Program into Program and ProgramBuilder

Browse Source 
Program is now immutable*, and remains part of the public Tint
interface.

ProgramBuilder is the mutable builder for Programs, and is not part of
the public Tint interface. ast::Builder has been folded into
ProgramBuilder.

Immutable Programs can be cloned into a mutable ProgramBuilder with
Program::CloneAsBuilder().

Mutable ProgramBuilders can be moved into immutable Programs.

* - mostly immutable. It still has a move constructor and move
  assignment operator - required for practical usage - and the
  semantic information on AST nodes is still mutable.
