This is in preparation to migrate package:kernel to null safety.
For the visitor interfaces to support non-nullable return types, the
implementations must avoid using `null` as return value in its base case.

Bug: https://github.com/dart-lang/sdk/issues/44797
This check was previously introduced without a language version,
and therefore lead to a breaking change on SDK update. It's now
versioned for releases >= 2.13, allowing users to migrate easier.
It also adds a hint for the error, providing alternatives for
users whose code triggers this check.

Adds static errors in web backends requiring external members to be
annotated with @JS(). Members can be annotated directly, or on the
enclosing class or library.
Also removes duplicate checks in dart2js for non-native external
members that are now covered by the checks on external @JS members.

Bug: https://github.com/flutter/flutter/issues/73176
This reverts commit 825f56c6aa.
Both ddc and dart2js keep a set of native class names to make sure
@JS() classes don't conflict. Instead of processing native classes
for every component, this CL caches the set of native classes. This
should address the recompile time issues related to the original
revert.

Checks to see if a JS interop member is correctly annotated with
the `external` keyword. If it is not, it must be one of several
exceptions to be allowed.
This CL also changes static errors to first check for `JS` and
`external` before processing the member as a JS interop member.
This makes it clearer whether a member is a JS member.

Towards #40434
Towards #38875Fixes#33834
- Add a shared error message for a non-external constructor.
- Check for non-external non-factory constructors constructors in the JS interop
checks.
- Remove commented out code in Dart2JS that used to handle this check.
- Clean up skipped tests due to the missing static error. The status in
`legacy_status_dart2js.csv` has no behavior impact but is removed for
completeness.
- Add `external` to a few test cases.
- Remove unused dart2js error message.
- Add `annotating` to hardcoded spelling list.
- Ignore missing example for web specific error message.
- Switch some dart2js error expectations to GENERIC since the message is no
longer defined with other dart2js errors.
Non-external synthetic constructors are ignored for now. An upcoming change will
automatically convert these to external.

Add a visitor that checks for invalid JS interop usage and reports
diagnostics. Wire the visitor up to the `DevCompilerTarget` and `Dart2jsTarget`.
- Add a message without an analyzer code for this error. In the long term we may
want to also add it to analyzer.
- Add a new package `_js_interop_checks` to share the kernel visitor between
dart2js and ddc. Some of the code is copied from ddc, and in the long term we
can centralize more of the detection of JS interop annotations to this
package.
- Implement the first check to detect definitions of `operator []` or
`operator []=` which are not allowed in JS interop classes.
