[Impeller] Create a global Vulkan instance in PlaygroundImplVK to prevent SwiftShader from being unloaded after a test completes (#47781)

Libcxx is leaking a thread-local storage key each time SwiftShader is
loaded and unloaded. If a test's Vulkan instance is the only one in the
process, then SwiftShader will be unloaded after the test ends. If many
Vulkan playground tests run in a suite, then eventually the leak will
cause the process to exceed its limit of TLS keys and the suite will
fail.

The process can ensure that SwiftShader remains loaded by holding
another Vulkan instance that persists across all tests in the suite.

Flutter Engine

OpenSSF Scorecard SLSA 1

Flutter is Google's SDK for crafting beautiful, fast user experiences for mobile, web, and desktop from a single codebase. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source.

The Flutter Engine is a portable runtime for hosting Flutter applications. It implements Flutter's core libraries, including animation and graphics, file and network I/O, accessibility support, plugin architecture, and a Dart runtime and compile toolchain. Most developers will interact with Flutter via the Flutter Framework, which provides a modern, reactive framework, and a rich set of platform, layout and foundation widgets.

If you want to run/contribute to Flutter Web engine, more tooling can be found at felt. This is a tool written to make web engine development experience easy.

If you are new to Flutter, then you will find more general information on the Flutter project, including tutorials and samples, on our Web site at Flutter.dev. For specific information about Flutter's APIs, consider our API reference which can be found at the docs.flutter.dev.

Flutter is a fully open source project, and we welcome contributions. Information on how to get started can be found at our contributor guide.
