[web] Better way to detect CanvasKit variant

[mdebbar]

Partial revert of #40027

For more info, see: https://skia-review.googlesource.com/c/skia/+/653416

The above CL introduces a new CanvasKit API to tell us whether it needs client ICU data or not. This allows us to do a more robust detection of the CanvasKit variant we are using.

BEFORE MERGING:

• Make a new CanvasKit release that contains the required changes, and roll to that version.
• We are now checking for the existence of the method before invoking it.

Fixes flutter/flutter#121905

If canvaskit_chromium also removes the wasm image codecs, then this should also add && browserSupportsImageDecoder. Although in practice, I'm not aware of any Chromium-based browser not supporting image decoders.

[mdebbar]

Agreed.

There's a timeout failure happening in wasm mode. This line is causing a hard wasm failure:

engine/lib/web_ui/lib/src/engine/dom.dart

Line 2164 in 161f759

final Object actualMethod = js_util.getProperty(o, method);

because the js_util.getProperty(...) patch in dart2wasm has the wrong signature (it shoud be Function(Object, Object) instead of Function(Object, String)).

This is being fixed in https://dart-review.googlesource.com/c/sdk/+/288161. (Thanks @joshualitt!). Once that Dart CL lands and rolls into the engine, I'll rebase and try again.

Thanks @eyebrowsoffire for looking into this with me!
