Add forceSingleThreadedSkwasm option to Flutter web loader (#178406)

[Ecraindrop]

Update initialization.md

This PR updates the Flutter web initialization documentation (initialization.md) to include the forceSingleThreadedSkwasm ption for _flutter.loader.load(). This option allows developers to force the Skia WebAssembly (skwasm) renderer to run in single-threaded mode, which improves compatibility in browsers that do not support multi-threaded WASM or when required security headers are missing.

Summary of Changes

Hello @Ecraindrop, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request updates the Flutter web initialization documentation to introduce a new configuration option, forceSingleThreadedSkwasm. This option allows developers to explicitly set the Skia WebAssembly renderer to operate in a single-threaded mode, which is crucial for ensuring broader compatibility across various browser environments, particularly where multi-threaded WASM is not supported or specific security headers are absent. The update includes a detailed explanation of the option's benefits and an example of its implementation.

Highlights

• Documentation Update: Added the forceSingleThreadedSkwasm option to the Flutter web initialization documentation, specifically within the _flutter.loader.load() configuration table.
• Skia WASM Renderer Compatibility: Detailed the purpose of forceSingleThreadedSkwasm, explaining its utility for forcing the Skia WebAssembly (skwasm) renderer into single-threaded mode to enhance compatibility in environments without multi-threaded WASM support or missing security headers.
• Example Usage: Included a clear JavaScript example demonstrating how to configure _flutter.loader.load() to use the forceSingleThreadedSkwasm: true option.

Thanks for the feedback! I’ve wrapped the long lines in the doc comment to comply with the 80-character limit and addressed the style issues from previous unapproved commits. Please let me know if there’s anything else that needs adjustment.
