The diagnostic applies to both the if-null expression ('??') and the
compound assignment expression ('??='), so it seems like the name should
be more general.

These fixes also prepare for an upcoming change to normalize FutureOr
types.
- Cache and emit the hoisted function type at the top level without
nullability wrappers.
- Always emit nullability wrappers at the use site.
- Fix issue where sometimes the return type would be double wrapped.

CSSStyleDeclaration.getPropertyValue returns a non-nullable string.
It will also return an empty string if the property is not found. Since
getPropertyValue returns the value of the native getPropertyValue, the
null check should be removed.

This is a breaking change. Request: https://github.com/dart-lang/sdk/issues/33501
HttpHeaders use lowercase by default for all headers, since it is supposed to be case insensitive. Some servers incorrectly treat case as significant, however, and expect headers with capitalization or in uppercase. The current implementation forces headers to be lower cases when adding values. Users cannot even manually modify the headers.
This change removes this restriction here so that users can modify the headers to whatever form they want. The new behavior is backwards compatible except if class was implemented. All headers inside http.dart are written as lower cases, adding values to HttpHeaders is still receiving lower cases input.
The other cl (https://dart-review.googlesource.com/c/http_multi_server/+/121411) migrates multi_headers.dart to be compatible with this change.

This temporarily:
* sets back to opt-out all libraries in the sdk_nnbd folder until
the migration is further along
* changes the bot to use the check_nnbd_sdk script with a different libraries
file that tracks the migration progress.

This is a reland of 344c584ec4
First attempt failed due to lack of implementation of the new
API from SDK in Flutter/engine that this change introduces.
Fixed by creating dummy implementation in flutter/engine:
https://github.com/flutter/engine/pull/16309
Original change's description:
> Implementation of evaluation to JS in frontend server
>
> - made ProgramCompiler somewhat incremental by letting the user
> set the current library and class
> - fixed a bug in procedure_builder where extension method wrappers
> did not have correct fileEndOffset set, which prevented finding
> dart scope at a line when extension methods are used
> - added new compileExpressionToJs API to frontend server and
> frontend compiler interface
> - added ExpressionCompier class that combines IncrementalCompiler
> and ProgramCompiler to compile expression at given dart location
> to JavaScript
> - in JavascriptBundle, set the module name for library tracking in
> JavaScript and saved program compilers to a table for incremental
> reuse in expression compiler
> - Exposed generator from IncrementalCompiler for use in
> ExpressionCompiler
> - added tests for expression compiler
> - added test for compileExpressionToJs API in frontend server tests
>

Optionals were being ignored for some methods and for optionals that
have a default of Undefined or None, they should be marked nullable in
Dart syntax regardless of whether they are in the IDL.

This is required when comparing functions type objects with sub-canonicalized functions.
Example:
Function() g() => (() => 0) (opt-out)
Function()? f() => null (opt-in)
both canonicalize their return type as a step in canonicalizing the entire function. Omitting a wrapper around the canonicalized function type (the return value) would result in the runtime types of these functions being canonicalized to the same value.

The constructor was wrapping the onData handler to hide the type-mismatch. This
copies the same logic to the onData handler.
In non-nnbd code this code was not exercised. The migration of dart:async
made this code reachable on our tests. That's because Stream.first used to
do:
var subscription;
this.listen(() => ... cancel subscription here, ...)
it now avoids making subscription nullable by registering the onData handler
later:
var subscrition = stream.listen(null, ...);
subscription.onData(() => ... cancel subscription here);
This change fixes the following 6 html tests under nnbd:
html/history_test/history/history
html/transferables_test
html/transition_event_test
html/websocket_test
html/worker_test/functional/functional
html/xhr_test
