This reverts commit 14414f35.

This reverts commit 160a5680.

This will manually land https://github.com/flutter/engine/pull/8983 in
the framework.

Instead of sharing the iOS codepath that uses an ObjC generated plugin
registrant and expecting plugins to have an ObjC interface layer, switch
to generating a Swift registrant and expecting plugins to have a Swift
interface.

This means plugins on macOS that use Swift won't need an ObjC wrapper,
and plugins that use ObjC will need a Swift wrapper (inverting the
structure relative to iOS).

When an AndroidView gains focus we invoke the(newly introduced)
'TextInput.setPlatformViewClient' text_input system channel method
which sets the platform view as the text input target.

When the AndroidView loses focus we send a clearFocus message to
platform views system channel(so the engine can clear the focus from
the platform view).

This PR is going to land before the engine implementation is rolled to
the framework, we swallow MissingPluginException for the newly
introduced method channel methods so this is a no-op before the engine
is ready(after the engine is rolled with the corresponding change I'll
remove the logic to swallow the exceptions).

The engine counterpart is in: flutter/engine#9203

Moves the logic for finding vcvars64.bat to a new VisualStudio class
that encapsulates finding, and providing information about, VisualStudio
installations. Adds a validator for it, and runs it for Windows
workflows in doctor.

This wasn't included originally since it didn't seem to be necessary for
macOS in testing, but not having it breaks Swift plugins. This matches
the iOS Swift Podfile template.

Creates a Material Design range slider.

The range slider is based off the updated slider, with the main difference being that it has 2 thumbs.
By default, the thumbs cannot pass each other and both the thumb and the value indicator create a stroke when they are overlapping for better visibility.

# Description
Currently the benchmarks test prints a scary warning message, even when it passes, that a benchmark is being run with asserts enabled.

Normally we don't want developers to do this, because the performance of code with asserts is not characteristic of what end-users will experience. However, we need to unit-test benchmarkWidgets, so I've added a contraindicated option to suppress the warning for the test.

This fixes a rather embarrassing bug in ShortcutManager that happened because I forgot to add the tests I meant to add.

This fixes the bug, and adds the tests.

See https://github.com/flutter/flutter/issues/31691

This adds support for game controller buttons. It adds some supplemental USB HID codes that aren't available from the Chromium source code, and maps those on Android to the game pad buttons that Android supports. Other platforms are not supported yet.
