Make shader warm-up async so it can handle image (#28687 )

## Description

This moves another 15-20ms from the animation jank of one of our important client to the startup latency. Unfortunately, this is probably not captured in our current benchmarks (presumably some other bottlenecks overshadow this shader compilation in the worst_frame benchmark). Considering that drawing images is such a common operation, maybe we should add one in the future to benchmark this.

We need this PR to land soon for our client because this changes the API to return Future.

Flutter Examples

This directory contains several examples of using Flutter. To run an example, use flutter run inside that example's directory. See the getting started guide to install the flutter tool.

For additional samples, see the flutter/samples repo.

Available examples include:

Hello, world The hello world app is a minimal Flutter app that shows the text "hello, world."
Flutter gallery The flutter gallery app showcases Flutter's widgets, including its implementation of material design.
Layers The layers vignettes show how to use the various layers in the Flutter framework. For details, see the layers README.
Platform Channel The platform channel app demonstrates how to connect a Flutter app to platform-specific APIs. For documentation, see https://flutter.io/platform-channels/.
Platform Channel Swift The platform channel swift app is the same as platform channel but the iOS version is in Swift and there is no Android version.

Notes

Note on Gradle wrapper files in .gitignore:

Gradle wrapper files should normally be checked into source control. The example projects don't do that to avoid having several copies of the wrapper binary in the Flutter repo. Instead, the Gradle wrapper is injected by Flutter tooling, and the wrapper files are .gitignore'd to avoid making the Flutter repository dirty as a side effect of running the examples.
