## Description

This PR is to make `InputDecorationTheme` conform to Flutter Material's
conventions for component themes:

- Added a `InputDecorationThemeData` class which defines overrides for
the defaults for `InputDecorator` properties.
- Added `InputDecorationTheme` constructor parameters:
`InputDecorationThemeData? data` and `Widget? child`. This is now the
preferred way to configure a `InputDecorationTheme`:

```dart
InputDecorationTheme(
	data: InputDecorationThemeData(
	    filled: true,
	    fillColor: Colors.amber,
	    ...
	  ),
  	child: const TextField()
)
```
These two properties are made nullable to not break existing apps which
has customized `ThemeData.inputDecorationTheme`.

- Update `InputDecorationTheme` to be an `InheritedTheme` subclass.
- Changed the type of component theme defaults from
`InputDecorationTheme` to `InputDecorationThemeData`.
- Changed the `InputDecorationTheme bottomAppBarTheme` property to
`Object? bottomAppBarTheme` in `ThemeData` and `ThemeData.copyWith()`
(Object? is used for the moment to minimize Google tests failure. A
follow-up PR will replace `Object?` with `InputDecorationThemeData`.
- Addresses the "theme normalization" sub-project within flutter#91772.

A migration guide will be created on website repo.
