Unpin DDS and roll pub packages

[DanTup]

DDS was temporarily pinned to 4.1.0 because 4.2.0 triggered some test failures (see #147250). Those failures should be fixed by vm_service 14.2.2, so this unpins DDS and rolls both of these packages (along with devtools_shared, which is a DDS dependency).

(If the bot updates vm_service before this is done, I can rebase over that will reduce the size of this PR to just a few files)

@bkonyi looks like the vm_service changes are failing some tests here:

 01:28 +4015 ~5 -2: test/general.shard\vmservice_test.dart: getFlutterViews polls until a view is returned

Example failing test is this one:

flutter/packages/flutter_tools/test/general.shard/vmservice_test.dart

Line 168 in 7920a52

testWithoutContext('setAssetDirectory forwards arguments correctly', () async {

I can repro locally, but it's not clear to me if what the test is doing is reasonable or not. It provides an empty stream as the input stream, which causes the method being tested to immediately be terminated as the service is disposed. I feel like it shouldn't be providing a stream that is closed before it has done its testing.. possibly it could close the stream after setAssetDirectory completes instead.

Thoughts? I can try the above, but want to make sure you don't think vm_service should handle this kind of code.

Yeah, this is a bad test. We should be using a FakeVmService that extends VmService and override the methods that are actually being called to return dummy data (I had to do something similar in google3).

Got it, I'll have a go :)

@christopherfujino @bkonyi I think this is good now (there's one bot outstanding as I type this, but the rest are green). There are some manual changes besides the pubspec changes to tidy up and fix some tests. You can type ".dart" in the file filter when looking at the changes to easily see the non-pubspec changes.

(cc @elliette in case you're interested in when this lands, it includes your permission-to-resume changes)
