[flutter_tool][gallery] Standardize target platform override behavior in tool and update flutter gallery to support it (#46206)

[flutter_tool] remove ability to disable Fingerprinter with DISABLE_FLUTTER_BUILD_CACHE env variable (#46913)

[flutter_tool] fix NPE in daemon caused by returning null connection info from experimental web runner (#46909)

* Prposal for supporting URL tunnelling

* Update daemon.md

* Add the ability for daemon to call clients to expose URLs

* Fix dwds mock in web_fs tests

* Fix type error

* Remove build_runner import from run

* Move appStartedTime back to after the app has started

* Remove nested DI scope and pass urlTunneller down

* Fix import

* Tweak TODO

* Fix existing tests

* Fix spec to use result instead of params for response object

* Fix exposeUrl to use a url field, as spec'd

* Test that the daemon's exposeUrl sends a request and handles the response

The variable debugDisableShadows wasn't reset before each test, so the
output of the test is different depending on whether the previous test
has passed.

* Make golden test timeout longer, some tests are flaky if the timeout is too short

* Enable some golden tests for web

* ExpandIcon should use the size parameter
