Daimona Eaytoy f8438a4647 Remove the old parser
All methods were moved to the new parser. Tests and other pieces were
adjusted to expect just a single parser. There are still some TODOs
(remove AFPTransitionBase, remove $this->mCur), but these are left for
another commit.

Note that the new parser was not renamed: this is because the names are
wrong anyway (CachingParser is more of an Evaluator than a Parser, and
AFPTreeParser is the real parser, and should be renamed as well).

NOTE to reviewers: this patch looks quite big, but if you diff the old
parser with the new version of the CachingParser, you'll notice that the
diff is actually small, since everything was basically copied verbatim.

Daimona Eaytoy e64049c30b Create dedicated types of parser exceptions
Introduce a clear distinction between internal exceptions and
user-visible exceptions, leaving AFPException as base abstract class.

Later, it should be possible to narrow some types around, e.g. in
ParserStatus (that might work with user-visible exceptions only).

Also a future TODO is putting all the exceptions in their own namespace
(probably ...\Parser\Exception).

Some cleanup is left for later to keep the diff easier to read.

Daimona Eaytoy d3b330b6d4 Create a VariablesManager service
This makes VariableHolder a true value object, and introduces a
stateless service, VariableManager, to operate on it.

Note, in theory, this new service is still cyclically coupled with
LazyVariableComputed. However, it's now two stateless service being
coupled, not two smart/god value objects, so we've still earned
something. For now, the dependency is hidden by using a callback. Some
alternatives for that are mentioned in a code comment.

Daimona Eaytoy 3e0c30ff92 Allow the parsers to return extra info
This is achieved by creating a new ParserStatus class. Aside from the
result of parse(), it contains whether the cache was warm. This can be
used to differentiate profiling data as part of T231112.

Another use case is returning non-fatal warnings (T269770).
