The @dart marker should only be used for released language versions,
rather than the upcoming release, since the upcoming language features
has not been finally assigned to a language version yet. The appropriate
experiments should be used instead to opt into upcoming features.
This change is part of the effort to make it possible to easily bump
tools/VERSION without unexpected issues whenever tests have to have
their pinned language versions updated as well.

- Add a new dart2js preamble file that seals the native object prototype.
- Use the file when running DDC in d8 locally.
Once this change lands the new preamble can be used in the script that
runs d8 on the benchmarking bots.
If benchmark results look good, I will followup with a change to enable
the prototype sealing in SDK test configurations as well.

Unfortunately our weekly bot that looks for leaks has been out of

This CL fixes the leak by overwriting the field every time, meaing we

Maybe ideally we shouldn't save it as a field at all, but that's a

Angular codegen emits members that are external so DDC's external
checks need to be more specific to only focus on JS interop. This
also modifies some code logic around whether a member is JS interop
to be less permissive. Before, it claimed that any member is JS
interop if it's external and the enclosing library has a @JS
annotation, but this is only true if there is no surrounding class.

With this change the Dart Core Object members (`.hashCode`,
`.runtimeType`, `.noSuchMethod()`, `.toString()`, and
`operator ==`) are no longer installed onto the native JavaScript
Object prototype. This is done because the Object prototype will be
sealed as a security precaution in some environments to avoid
prototype pollution exploits.
This means that dispatching to these APIs will change when the
compiler cannot know if the receiver may be null or a value from
JavaScript interop. In those cases a call to a helper method is
inserted instead. The helpers will probe for the API on the value,
call it if available or execute a default version.
NOTE: Many other native JavaScript prototypes are still modified. This
change is only for the Object prototype.
