dart:js_interop and package:js will start conflicting, since they both have an `@JS` annotation. Until we're ready to only use dart:js_interop (which will require updating the SDK constraints of every package), we should hide the `@JS` annotation from dart:js_interop. Due to shadowing, this is the behavior today, so there should be no functional change.

Unblocks https://dart-review.googlesource.com/c/sdk/+/294130/8 and prevents confusing shadowing of dart:js_interop annotations like we do today.

Remove double.fromEnvironment from dart-define doc.

Fixes #124665 

The current dart-define docs reads:

```
Additional key-value pairs that will be available as constants from the String.fromEnvironment, bool.fromEnvironment, int.fromEnvironment, and
double.fromEnvironment constructors.
```
while dart-define-from-file reads:

```
The path of a json format file where flutter define a global constant pool. 
Json entry will be available as constants from the String.fromEnvironment, bool.fromEnvironment, int.fromEnvironment, 
and double.fromEnvironment constructors; the key and field are json values
```

However, there is no fromEnvironment constructor for double. The aim of this PR is to address this by removing double.fromEnvironment from help docs as stated in

This is motivated by part of the 2D scrolling proposal: [flutter.dev/go/2D-Foundation](https://flutter.dev/go/2D-Foundation)

This is one of the last little PRs to prep for the 2D scrolling foundation. 
This adds an optional `axis` parameter to the static Scrollable methods `[of, maybeOf, recommendDeferredLoadingForContext]`. This allows developers that are nesting scrollables (or one day using 2D scrolling) to look them up instead by a particular axis.

In general, even outside the context of 2D, I think this is helpful. I am often asked how to get the outer scrollable when nesting. Now it can be done.

There is also a small semantic refactor here in ScrollableState.build, this just creates a private method (_buildChrome) that will be overridden in 2D later. It is easier to add now than in the really big PR that will be.

Just found this while trying to run the integration test shard of `flutter_tools` locally :)
