## Description
This PR adds `DropdownMenuFormField.decorationBuilder` and passes it to
the underlying `DropdownMenu`.
## Related Issue
Follow-up to https://github.com/flutter/flutter/pull/176264 which added
`DropdownMenu.decorationBuilder`.
## Tests
- Adds 1 test.
Flutter needs a strong story around pausing animated GIFs because it
affects accessibility via
[MediaQueryData.disableAnimations](https://main-api.flutter.dev/flutter/widgets/MediaQueryData/disableAnimations.html).
See https://github.com/flutter/flutter/issues/175516.
### Today
Currently, it's possible to pause a gif using TickerProvider. However,
if paused on initial load, the first frame will never display, and I
believe that's a bug.
```dart
TickerMode(
// Pauses the gif, but if set to false on first load, the first frame never loads.
enabled: false,
child: Image(image: myAnimatedGif),
),
```
Currently `disableAnimations` has no effect:
```dart
MediaQuery(
// Currently has no effect on the Image, until this PR.
data: MediaQueryData(disableAnimations: true),
child: Image(image: myAnimatedGif),
),
```
### With this PR
* MediaQueryData.disableAnimations can be used to pause a gif in the
same way that TickerMode can be used today.
* If either MediaQuery.disableAnimations or TickerMode cause a gif to be
paused on first load, it will show its first frame before pausing. This
is potentially a breaking change.
* The docs clearly explain this behavior and how to pause a gif.

# Framework:
* `EditableText`/`SelectableText`, applies
`lineHeightScaleFactorOverride`, `wordSpacingOverride`, and
`letterSpacingOverride` to it's `TextStyle` similarly to how we already
do for bold platform overrides. Note `SelectableText` is built on
`EditableText` so it also applies these overrides.
* `Text`, applies `lineHeightScaleFactorOverride`,
`wordSpacingOverride`, and `letterSpacingOverride` to it's `TextStyle`
similarly to how we already do for bold platform overrides.
* Exposes line height override through
`MediaQueryData.lineHeightScaleFactorOverride` and
`maybeLineHeightScaleFactorOverrideOf(context)`.
* Exposes letter spacing override through
`MediaQueryData.letterSpacingOverride` and
`maybeLetterSpacingOverrideOf(context)`.
* Exposes word spacing override through
`MediaQueryData.wordSpacingOverride` and
`maybeWordSpacingOverrideOf(context)`.
* Exposes paragraph spacing override through
`MediaQueryData.paragraphSpacingOverride` and
`maybeParagraphSpacingOverrideOf(context)`.
* `MediaQuery.applyTextStyleOverrides()` \
`MediaQueryData.applyTextStyleOverrides()` to be able to reset/override
the text spacing settings on `MediaQueryData`.
# Engine:
* Introduces new members on `PlatformDispatcher` API that hold the text
spacing properties that are overridden on the web.
* We provide the `lineHeightScaleFactorOverride`,
`letterSpacingOverride`, `wordSpacingOverride`, and
`paragraphSpacingOverride` on the web by attaching a `ResizeObserver` to
an off-screen hidden element, when its size changes we capture its text
spacing CSS properties, and notify the framework through
`onMetricsChanged`.

Android touch events include updates to multiple pointers, but each
pointer data message sent from the embedder to the framework represents
a single pointer. So the Android embedder will send multiple messages
for each touch event, and the framework's AndroidViewController will
reassemble the messages and forward the resulting event to the platform
view.
The AndroidViewController tracks the number of active pointers in its
own local state. If that state is out of sync with the event handled by
the Android embedder, then the AndroidViewController may send duplicate
events to the platform view.
This PR encodes the Android touch event's pointer count in the messages
sent to the framework. This allows the AndroidViewController to reliably
determine whether it has received all of the pointer messages that
originated from an event.

### Description
- Moves `MenuButton` submit logic from `onEditingComplete` to
`onSubmitted` to allow `TextField` to handle the `textInputAction` logic
- Wraps each item into `ExcludeFocus` to enable proper
`TextInputAction.previous` handling. If we don't wrap each child in
`ExcludeFocus`, then focus will be moved to one of them, which is not
the expected behavior for `TextInputAction.previous`.

crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.center,
spacing: 20,
children: [
TextField(

DropdownMenu<String>(

textInputAction: TextInputAction.next,
onSelected: (String? color) {
print('SELECTED $color');
},
dropdownMenuEntries: [
DropdownMenuEntry(value: 'red', label: 'red'),
DropdownMenuEntry(value: 'green', label: 'green'),
DropdownMenuEntry(value: 'blue', label: 'blue'),
],

TextField(
focusNode: _nextFocusNode,
textInputAction: TextInputAction.done,
decoration: InputDecoration(
border: OutlineInputBorder(),
labelText: 'Next TextField',
),
),
],
),
),
),
);
}
}
```
</details>
There is still one behavior I would like to discuss. When the
`showTrailingIcon: true` and `textInputAction: TextInputAction.previous`
are used, the focus moves not to the previous field but to the
`IconButton`. If we wrap the `IconButton` with `ExcludeFocus`, then this
is fixed, but I am not sure whether this is the correct way to proceed.

This function doesn't seem to serve any purpose.
Top level is not a term we are currently using in the multi window code.
If we want to track if we have open windows, this can be done in the
Flutter framework - it doesn't need to be done at the platform level.
