Add Printer::Sub for finer configuration of how a variable substitution is processed.

In particular, this allows for configuring what the "consume after" characters that follow
a $...$ are, which previously were ";," for callback subs and "" for everything else.

In a followup the three-argument constructor for Sub will be removed and replaced with
calls to Annotate().

Also, calls to WithVars still reject closure arguments, but this check happens at runtime
now. This is a minor papercut for users that simplifies the implementation of Sub and
related private types immensely.
