Front-end server and gen_kernel tools now take
--dump-detailed-dynamic-interface=foo.json
option which can be used along with --dynamic-interface when
AOT-compiling application with exposed dynamic interface.
This option dumps dynamic interface broken down to members
and classes as JSON.

When const constructor is exposed through a dynamic interface,
dynamic module can create constants with that const constructor and
it can reference everything used in that constructor including default
values of parameters and field initializers. So dynamic interface
annotator should visit bodies of const constructors and add all
references to implicit uses.
Annotator should also visit initializers of instance fields of
classes which can be used in a constant (as they participate in
the constant evaluation too). Kernel trim tool should not remove such
field initializers.

Mixin transformation copies members of a mixin into a mixin
application class. Copied members should still behave similarly to
original members in terms of overriding.
When validating a dynamic module, overriding a copy of mixin
member should be allowed if original member can be overridden.
When annotating AST with dynamic interface pragmas, can-be-overridden
pragmas should apply to all copies of mixin members.

Dynamic module validation now accepts reference to classes and members
from 'dart:*' libraries if they are annotated with
dyn-module:language-impl:* pragmas. This matches the behavior of
dynamic interface annotator.
This is a follow-up to
https://dart-review.googlesource.com/c/sdk/+/418663.
Also, when checking for possible dynamic overrides in TFA,
treat _enumToString from dart:core as a public name because
front-end desugars enums into classes which override
private _enumToString method in a different library.

This change adds pragmas which can be used in dart:* libraries to
specify classes and members which are used by the compiler
to implement certain language features. Compiler can insert
references to those classes and members when desugaring language
constructs, so dynamic module code can use these classes and members
implicitly even if they are private.
Previously, we required to specify these members in the
dynamic_interface.yaml before dynamic modules could use them.
However, this is cumbersome and error-prone.
Now, the following pragmas are recognized:
@pragma('dyn-module:language-impl:extendable')
@pragma('dyn-module:language-impl:can-be-overridden')
@pragma('dyn-module:language-impl:callable')
If dynamic interface yaml file is specified during compilation,
then classes/members annotated with these pragmas are treated as if
they are used in corresponding sections of dynamic_interface.yaml.
If dynamic interface yaml file is not specified, these pragmas
are ignored.

Consider the following situation: member M1 is overridden by another
member M2; M2 is overridden in a dynamic module.
Members which can be overridden in a dynamic module (such as M2)
should be specified as 'can-be-overridden' in the dynamic interface.
Members which are overridden implicitly/transitively (such as M1)
are not required to be mentioned in the dynamic interface.
However, when determining possible targets for a call with
interface target M1, compiler should treat it as potentially
overridden in a dynamic module.
This change adds such handling to the VM/AOT. Dynamic interface
annotator now marks members such as M1 with
'dyn-module:can-be-overridden-implicitly' pragma, and
VM/AOT takes both can-be-overridden and can-be-overridden-implicitly
into account.
This change also simplifies handling of implicitly extenable classes
in the VM/AOT - now VM handles both extendable and implicitly-extendable
pragmas (from dynamic interface annotator) instead of recalculating
implicitly extendable classes on its own.

All supertypes of classes marked as "dyn-module:extendable" are technically also extendable in dynamic modules since subtyping is transitive.
Also skip marking 'final' classes as dynamic module extendable.

* Introduce steps to execute tests in AOT (using gen-kernel,
dart2bytecode, and aot compiler)
* Accept using filesystem-scheme to provide dynamic_interfaces.yaml input
* Accept empty dynamic_interfaces.yaml
* Make temporary test changes to get them running:
* include core types in dynamic_interfaces that we may want to have
by default
* rename entrypoint to `main`
Most existing test pass, the two tests that validate that a library
cannot be defined twice fail (expectation is to throw, bytecode ignores
the second definition).
To run locally:
```
./tool/build.py -m release --dart-dynamic-modules create_sdk

Dynamic interface annotator now automatically annotates classes and
members which are used implicitly:
* Targets of redirecting factories.
* Classes and members used in constants.
* Instance fields of classes used in instance constants or
having a callable const constructor.
* Everything used in the bodies of extendable mixin declarations and
mixin classes.
* Possible dispatch targets of instance calls
(overrides/implementations).
Front-end server now also exposes '--dynamic-interface' option,
similar to gen_kernel tool.
Also, this change includes a couple of minor fixes:
* Typo in ast.dart.
* In the front-end server, additional dill file specified with
'--import-dill' option is not ignored when '--link-platform' is
also used.
