Deprecate `textScaleFactor` in favor of `textScaler`, in preparation for Android 14 [Non-linear font scaling to 200%](https://developer.android.com/about/versions/14/features#non-linear-font-scaling). The `TextScaler` class can be moved to `dart:ui` in the future, if we decide to use the Android platform API or AndroidX to get the scaling curve instead of hard coding the curve in the framework.
I haven't put the Flutter version in the deprecation message so the analyzer checks are failing. Will do so after I finish the migration guide.
**Why `TextScaler.textScaleFactor`**
The author of a `TextScaler` subclass should provide a fallback `textScaleFactor`. By making `TextScaler` also contain the `textScaleFactor` information it also makes it easier to migrate: if a widget overrides `MediaQueryData.textScaler` in the tree, for unmigrated widgets in the subtree it would also have to override `MediaQueryData.textScaleFactor`, and that makes it difficult to remove `MediaQueryData.textScaleFactor` in the future.
## A full list of affected APIs in this PR
Deprecated: The method/getter/setter/argument is annotated with a `@Deprecated()` annotation in this PR, and the caller should replace it with `textScaler` instead. Unless otherwise specified there will be a Flutter fix available to help with migration but it's still recommended to migrate case-by-case.
**Replaced**: The method this `textScaleFactor` argument belongs to is rarely called directly by user code and is not overridden by any of the registered custom tests, so the argument is directly replaced by `TextScaler`.
**To Be Deprecated**: The method/getter/setter/argument can't be deprecated in this PR because a registered customer test depends on it and a Flutter fix isn't available (or the test was run without applying flutter fixes first). This method/getter/setter/argument will be deprecated in a followup PR once the registered test is migrated.

A lot of material widgets (`Slider`, `RangeSlider`, `TimePicker`, and different types of buttons) also change their layout based on `textScaleFactor`. These need to be handled in a case-by-case fashion and will be migrated in follow-up PRs.
This PR changes the example app into a custom scrollview with three slivers. The middle sliver has a nested scrollview of height 300 and only this nested sliver can trigger the refresh indicator.
Fixes https://github.com/flutter/flutter/issues/116237.
This change updates `SelectableRegion`s right-click gesture to match native platform behavior.
Before: Right-click gesture selects word at position and opens context menu (All Platforms)
After:
- Linux, toggles context menu on/off, and collapses selection when click was not on an active selection (uncollapsed).
- Windows, Android, Fuchsia, shows context menu at right-clicked position (unless the click is at an active selection).
- macOS, toggles the context menu if right click was at the same position as the previous / or selects word at position and opens context menu.
- iOS, selects word at position and opens context menu.
This change also prevents the `copy` menu button from being shown when there is a collapsed selection (nothing to copy).
Fixes#117561
## Description
Changes the context menu example for `MenuAnchor` so that it uses right-click, or (on macOS and iOS only) ctrl-left-click, for the context menu. Also disables the browser context menu on web platforms.
## Tests
- Updated test to reflect new triggers.
Updated the ToggleButtons example and test to M3.
Updated the nested tabs test to avoid warnings like:
```
Warning: A call to tap() with finder "exactly one widget with type "Tab" which is an ancestor of text "Explore": Tab(text: "Explore", icon: Icon)" derived an Offset (Offset(666.7, 92.0)) that would not hit test on the specified widget.
```
This example was incorrectly throwing away results from a query when multiple queries were pending at once. Thanks to @sun-jiao in https://github.com/flutter/flutter/pull/127019#issuecomment-1552347037 for pointing this out.
I also added a quick `Text` widget explaining what to do to use the examples. Since there are only three small possible `options`, it's easy to type into the field and not get any results and wonder what's wrong.
