Refactor parser Checkpoints.

Why this is better:

1) Not needing an extra template parameter for Checkpoints ctors. This was
especially confusing since the template parameter was named Parser and Parser is
also used as a type name and is also a concrete type. This CL makes it clear
that ParserTraits::Checkpoint is consturcted with ParserBase<ParserTraits> -
that's the only sensemaking type for the ctor param anyway.

2) This CL makes ParserBase define a Checkpoint base class (which knows how
to create and restore a checkpoint with ParserBase) which
PreParserTraits::Checkpoint and ParserTraits::Checkpoint inherit, and not the
other way around.

This is a more intuitive way to implement the "base functionality + extending
it" concept than the previous solution. The previous solution was to allow
Traits to define a Checkpoint class and make ParserBase<Traits>::ParserCheckpoint
(which defines the base functionality) inherit from it.

3) This CL moves the Checkpoint class definitions out of the SomeTraits::Type
struct; SomeTraits::Type is supposed to be a collection of typedefs and not
contain anything else.

Checkpoints were introduced in r22925 ( https://codereview.chromium.org/443903003 ).
