Possible fix for flutter#169574 It looks like the timeouts seem to be specific to downloading scripts. Specifically, after a certain point, we no longer download any scripts. Lowering the number of max concurrent requests seems to avoid Chrome timing out.

I'm going to try seeing if I can repro any timeouts with this max queue size in my test/logging PR. |

…70565) Possible fix for flutter#169574 It looks like the timeouts seem to be specific to downloading scripts. Specifically, after a certain point, we no longer download any scripts. Lowering the number of max concurrent requests seems to avoid Chrome timing out. This does a refactor as well to make sure we're piping FileSystem, Logger, and Platform into devfs_web.dart instead of relying on globals every time. This also fixes a test issue where we were always passing `isWindows: false` in some test cases instead of checking for the value. ## Pre-launch Checklist - [x] I read the [Contributor Guide] and followed the process outlined there for submitting PRs. - [x] I read the [Tree Hygiene] wiki page, which explains my responsibilities. - [x] I read and followed the [Flutter Style Guide], including [Features we expect every widget to implement]. - [x] I signed the [CLA]. - [x] I listed at least one issue that this PR fixes in the description above. - [x] I updated/added relevant documentation (doc comments with `///`). - [x] I added new tests to check the change I am making, or this PR is [test-exempt]. - [x] I followed the [breaking change policy] and added [Data Driven Fixes] where supported. - [x] All existing and new tests are passing.
