Closes https://github.com/dart-lang/sdk/issues/54192
Callbacks were being casted to their static type before being
called. With generic callbacks, we do not know their exact type
at compile time, therefore cannot make that cast. Similarly, a
null check was being done if the static type of the parameter
was potentially non-nullable, whereas it should be done if it's
*not* potentially nullable.

Addresses some comments in https://github.com/dart-lang/sdk/issues/54192
- With the addition of `nonTypeVariableBound`, we no longer need a
recursive checker.
- We also should account for `StructuralParameterTypes`.
- The current checks did not check type parameters for functions
converted via `toJS`, so that is handled as well.
- Functions that declare type parameters cannot be called in JS
correctly, so an error is added when users try to convert them.
- Some errors are reworded/modified.

- Removes @staticInterop JS types declarations in favor of
typedefs (the function types' reified types and the typed data's
reified types have changed to make the type hierarchy work in the
JS backends).
- Adds extension types to dart:js_interop
- Adds a fromInteropObject helper to JSObject to avoid casting to
an extension type
- Deletes now stale tests
- Refactors some dart2wasm @staticInterop declarations since they
can no longer implement JS types
- Updates extension types tests to use the prefix extension_type
instead of inline_class
- Updates comments

Users are allowed to have extension types on types that we allow
on external methods e.g. String. For most types, this doesn't make a
difference as we jsify for parameters and dartify and cast for return
types. The one place it does matter is when we check the static type
to do int conversions. Here, we should use the erased type instead.

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.

Determines the ultimate representation type of an inline class to
determine if it can use external members. This allows users to
elide @JS if they don't need renaming. This CL adds some static
errors around inline interop members so its clearer that the

There's a bit of cleanup in this CL too around interop members,
where extension members on @Native classes are now correctly
considered as interop members by the error checker.
