Support Flutter Web WASM symbolication

[marandaneto]

Description

JS package -> https://github.com/getsentry/sentry-javascript/tree/develop/packages/wasm The SDK needs to fill the debug_meta property with the image list. Flutter Web probably exposes the WebAssembly.Module as well, if not, we can leverage that by using the JS SDK directly. The Dart plugin should upload the DWARF files.

SDKs cannot depend on html packages nor its transitive dependencies https://docs.flutter.dev/platform-integration/web/wasm#requires-preview-js-interop-to-access-browser-and-js-apis

Sentry Flutter SDK isn't compatible as of now. Sentry Dart SDK compiles just fine.

Blocked by https://github.com/flutter/flutter/issues/127564 as well

Dart SDK compiles but it does not work either. We have to guard every call that depends on dart.library.html or dart.library.io to a no-op call. we do this most of the time but there are probably a few exceptions not considered because we always assume it's either one or the other.

runtime parsing can also be improved, currently (dart2wasm used in tests and introduced in #2113) we get this:
