Trim mixins from stack frame names in debugger
In the timeline, we were getting extremely long class names for stack frames. _WidgetsFlutterBinding&BindingBase&GestureBinding&ServicesBinding&SchedulerBinding&PaintingBinding&SemanticsBinding&RendererBinding._handlePersistentFrameCallback
The important information here would be _WidgetsFlutterBinding._handlePersistentFrameCallback, and is what we show in the profiler UI as of https://github.com/flutter/devtools/pull/706.
We may have a similar issue in the debugger UI, and should address it there as well.
Fyi @bkonyi We should really fix this in the VM itself as these long names just confuse users.
Original issue for that here: https://github.com/dart-lang/sdk/issues/36999
@jacob314, as discussed in dart-lang/sdk#36999 this isn't something we're planning on doing in the VM itself. However, this could be some functionality that lives in package:vmservice. If the VM team eventually takes over that package once we've gotten everyone off of using private APIs, we'd be happy to add it there.
Let me follow up on the dart-sdk issue. The key point is the names with & are a misfeature and we should modify the VM so it never generates those names in the first place. I'll update the SDK bug ccing interested language team members.
