[web] Remove all usages of js_util. (#171871)
Closes https://github.com/flutter/flutter/issues/143396

### Description
- Removes `js_util` library usage across the codebase

In order to get rid of `dart.library.js_util` in
[`kIsWeb`](e8d56b25c0/packages/flutter/lib/src/foundation/constants.dart (L83))
constant the dart analyzer has to be updated first. For now, the
`dart.library.js_util` value is hardcoded in the source code:
1a88edceb7/pkg/analyzer/lib/src/dart/constant/evaluation.dart (L2908-L2915).
So we either have to update this value or wait for the
https://github.com/dart-lang/sdk/issues/50045 fix.

Flutter Web integration tests

To run the tests in this package download the chromedriver matching the version of Chrome. To find out the version of your Chrome installation visit chrome://version.

Start chromedriver using the following command:

chromedriver --port=4444

An integration test is run using the flutter drive command. Some tests are written for a specific web renderer and/or specific build mode. Before running a test, check the _runWebLongRunningTests function defined in dev/bots/test.dart, and determine the right web renderer and the build mode you'd like to run the test in.

Here's an example of running an integration test:

flutter drive --target=test_driver/text_editing_integration.dart \
  -d web-server \
  --browser-name=chrome \
  --profile

This example runs the test in profile mode (--profile).
