This is a bare-bones implementation (and test) for having an explicit
toString on all `Node`s.
This can then be extended as-needed to better suit our debugging
purposes. It's not allowed to leak, though.

Add support for the `late` modifier on fields and local variables in
CFE, and `required` on named parameters When using the option
--enable-experiment=non-nullable the `isLate` and `isRequired` flags will be set
accordingly on Field and VariableDeclaration nodes.

Adds Extension node to kernel/ast, currently with serialization. This
is needed to support resolution of extension methods through dill
boundaries.
Adds (Source)ExtensionBuilder for build Extension nodes and
DeclarationBuilder as common superclass of ClassBuilder and
ExtensionBuilder.

Make sure to use Printer methods when formatting class references
instead of going through TreeNode.toString which uses globalNames
instead of Printer's own syntheticNames.

During constant evaluation, unused arguments to a const constructor are
thrown away after evaluation, since their values do not affect the
resulting instance constant. If such an unused argument ends up
unevaluated, any errors that would arise in the final evaluation are
not reported.
This CL adds space in the Kernel AST for saving these unevaluated
expressions so they can be checked during final constant evaluation.
Even though this is an incompatible change, no update is needed to the
VM code (except for the version bump), since the VM does not support
InstanceCreation nodes in the first place.

This change replaces kernel AST declarations of fields and functions
with bytecode declarations.
Size of dilp files is reduced by 11-12%.
Startup latency:
Time to the first full frame: 1.945s -> 1.687s
FinalizeClass: 554ms -> 277ms
FinishClassLoading: 296ms -> 156ms
There are following regressions in bytecode mode, which will be fixed
in future:
* dart:mirrors are not supported yet (implementation of mirrors relies
on reading kernel AST in certain cases).
As the result, lib_2/mirrors/* tests fail.
* native extensions are not supported yet (annotations on libraries
and classes in AST are cleaned up as they could reference members
which are now removed from AST).
As the result, standalone_2/entrypoints_verification_test test fails.
* language_2/spread_collections/const_error_test/* tests fail
due to https://github.com/dart-lang/sdk/issues/36286.

These arise when the constant evaluator partially evaluates collections
containing spreads or control-flow constructs with unevaluated
subexpressions. They are removed by the final constant evaluation.

Having a block as body instead of a list of expressions simplifies
code handling block expressions. Since it is always a block, it can
be left untagged in the serialized representation so the serialized
representation is not changed with this change.
