It's now possible to use the native-rendered text selection context menu on iOS. This sacrifices customizability in exchange for avoiding showing a notification when the user presses "Paste". It's off by default, but to enable, see the example system_context_menu.0.dart.

In order to work around the fact that iOS 15 shows a notification on pressing Flutter's paste button (https://github.com/flutter/flutter/issues/103163), this PR allows showing the iOS system context menu in text fields.
<img width="385" alt="Screenshot 2024-02-06 at 11 52 25 AM" src="https://github.com/flutter/flutter/assets/389558/d82e18ee-b8a3-4082-9225-cf47fa7f3674">
It is currently opt-in, which a user would typically do like this (also in example system_context_menu.0.dart):
```dart
contextMenuBuilder: (BuildContext context, EditableTextState editableTextState) {
// If supported, show the system context menu.
if (SystemContextMenu.isSupported(context)) {
return SystemContextMenu.editableText(
editableTextState: editableTextState,
);
}
// Otherwise, show the flutter-rendered context menu for the current
// platform.
return AdaptiveTextSelectionToolbar.editableText(
editableTextState: editableTextState,
);
},
```
Requires engine PR https://github.com/flutter/engine/pull/50095.
## API changes
### SystemContextMenu
A widget that shows the system context menu when built, and removes it when disposed. The main high-level way that most users would use this PR. Only works on later versions of iOS.
### SystemContextMenuController
Used under the hood to hide and show a system context menu. There can only be one visible at a time.
### MediaQuery.supportsShowingSystemContextMenu
Sent by the iOS embedder to tell the framework whether or not the platform supports showing the system context menu. That way the framework, or Flutter developers, can decide to show a different menu.
### `flutter/platform ContextMenu.showSystemContextMenu`
Sent by the framework to show the menu at a given `targetRect`, which is the current selection rect.
### `flutter/platform ContextMenu.hideSystemContextMenu`
Sent by the framework to hide the menu. Typically not needed, because the platform will hide the menu when the user taps outside of it and after the user presses a button, but it handles edge cases where the user programmatically rebuilds the context menu, for example.
### `flutter/platform System.onDismissSystemContextMenu`
Sent by the iOS embedder to indicate that the system context menu has been hidden by the system, such as when the user taps outside of the menu. This is useful when there are multiple instances of SystemContextMenu, such as with multiple text fields.
It's now possible to use the native-rendered text selection context menu on iOS. This sacrifices customizability in exchange for avoiding showing a notification when the user presses "Paste". It's off by default, but to enable, see the example system_context_menu.0.dart.

### Description
- Updates `examples/api/lib/widgets/animated_size/animated_size.0.dart` API example by using `SizedBox` to size the surrounding of the `FlutterLogo` while setting the constant `FlutterLogo` size. This was done because `FlutterLogo` already has size animation under the hood, and the main goal of this example is to show `AnimatedSize` usage

## Description
This fixes an issue in the creation of the `FocusScope` in a route: the route should be creating the `FocusScope` widget it has with `withExternalFocusNode`, since it is modifying the node attributes in a builder.
Also modified some `AnimatedBuilder`s to be `ListenableBuilder`s, since they're not using animations (no functionality change there, since the implementation of the two is identical).

## Description
This adds some "See also" links to some docs for `TweenAnimationBuilder` and `ValueListenableBuilder`.
Also, moved a "snippet" example in `ValueListenableBuilder` into the examples directory as a Dartpad example.
## Tests
- Added test for the example.
The original PR was reverted because the new caret positioning callpath triggered a skparagraph assert. The assert has been removed. Relanding the PR with no changes applied.

Original Description:
The behavior largely remains the same, except:
1. The EOT cursor `(textLength, downstream)` for text ending in the opposite writing direction as the paragraph is now placed at the visual end of the last line.
For example, in a LTR paragraph, the EOT cursor for `aA` (lowercase for LTR and uppercase for RTL) is placed to the right of the line: `aA|` (it was `a|A` before).
This matches the behavior of most applications that do logical order arrow key navigation instead of visual order navigation.
And it makes the navigation order consistent for `aA\naA`:
```
|aA => aA| => aA| => aA => aA => aA
aA aA aA |aA aA| aA|
(1) (2) (3) (4) (5) (6)
```
This is indeed still pretty confusing as (2) and (3), as well as (5) and (6) are hard to distinguish (when the I beam has a large width they are actually visually distinguishable -- they use the same anchor but one gets painted to the left and the other to the right. I noticed that emacs does the same).
But logical order navigation will always be confusing in bidi text, in one way or another.
Interestingly there are 3 different behaviors I've observed in chrome:
- the chrome download dialog (which I think uses GTK text widgets but not sure which version) gives me 2 cursors when navigating bidi text, and
- its HTML fields only show one, and presumably they place the I beam at the **trailing edge** of the character (which makes more sense for backspacing I guess).
- On the other hand, its (new) omnibar seems to use visual order arrow navigation
Side note: we may need to update the "tap to place the caret here" logic to handle the case where the tap lands outside of the text and the text ends in the opposite writing direction.
2. Removed the logarithmic search. The same could be done using the characters package but when glyphInfo tells you about the baseline location in the future we probably don't need the `getBoxesForRange` call. This should fix https://github.com/flutter/flutter/issues/123424.
## Internal Tests
This is going to change the image output of some internal golden tests. I'm planning to merge https://github.com/flutter/flutter/pull/143281 before this to avoid updating the same golden files twice for invalid selections.

## Description
This PR adds more documentation for `TextEditingController(String text)` constructor and it adds one example.
https://github.com/flutter/flutter/pull/96245 was a first improvement to the documentation.
https://github.com/flutter/flutter/issues/79495 tried to hide the cursor when an invalid selection is set but it was reverted.
https://github.com/flutter/flutter/pull/123777 mitigated the issue of having a default invalid selection: it takes care of setting a proper selection when a text field is focused and its controller selection is not initialized.
I will try changing the initial selection in another PR, but It will probably break several existing tests.
