[stable] Roll latest dart_style into the SDK.

The fixes are:

1. Comments in switch expressions would force the next line to split:

```
// Before:
return switch (level) {
  0 => a,
  // Comment.
  1
      when flag =>
    b,
};

// After:
return switch (level) {
  0 => a,
  // Comment.
  1 when flag => b,
};
```

2. Method calls on split record literals split before the ".":

```
// Before:
final a = (
  element,
  element,
)
    .getter;

// After:
final a = (
  element,
  element,
).getter;
```

3. Change how parameter metadata is formatted:

```
// Before:
function(
    @required
        int n,
    @deprecated('Some long deprecation string.')
        String s) {
  ...
}

// After:
function(
    @required int n,
    @deprecated('Some long deprecation string.')
    String s) {
  ...
}
```

This change also significantly improves performance in rare cases where
a function has many parameters.
