Ben Clayton 8d98977a30 [tint][ir] Make the ir::BuilderImpl PIMPL
Black-box the BuilderImpl by putting the BuilderImpl into the
from_program.cc file.

Why:

* It means there's only a single definition of all the methods that need
  to be maintained, instead of pointlessly splitting code between two
  files (.cc / .h).
* It removes all the implementation details from the header.
* It removes a whole bunch of transitive includes, slowing compiles.
* It prevents the temptation for future #includes to
  private-implementation details.
* It reduces the amount of symbols declared outside of anonymous
  namespaces, reducing symbol polution and the amount of work on the
  linker.
