* Send an event at startup with the protocol version and pid
The pid will help with some of the issues of terminate the process when launched through a shell script and the version will allow clients to make decisions about supported features.
I've also bumped the protocol version number for two reasons:
1. This change
2. We didn't increase it when we added the previous emulator commands

* Add a `debugInstrumentAction()` method that will wrap an action
in a stopwatch and print the time it took to run the action.
* Add a global `debugInstrumentationEnabled` that will control
whether `debugInstrumentAction()` does anything (even in debug
builds).
* Add some basic instrumentation to `registerServiceExtension()`
* Temporarily enable the `debugInstrumentationEnabled` flag in the
Gallery to give us better visibility into what's happening in

When running with --local-engine, build single-architecture apps, rather
than what's declared in the Xcode project.
By default, Flutter creates Xcode projects that generate universal
binaries supporting both armv7 and arm64 processors. Since local engine builds
are all single-architecture, override the Xcode project's ARCHS setting
with the appropriate value for the specific engine.
NOTE: this assumes engine paths consistent with those used in the engine
repo: 32-bit iOS engine builds end in _arm, 64-bit builds do not.
It should be calling `tile.getDistanceToActualBaseline()` rather than
`tile.getDistanceToBaseline()`. This is causing us to hit assertions
`getDistanceToBaseline()`
* Fix#16464: Pass hit test when a big child is inside RenderFittedBox, RenderTransform, RenderFractionalTranslation, or RenderFollowerLayer
* Override `hitTestChildren`
* RenderTransform and RenderFollowerLayer shouldn't check if they are hit
themselves
* Test the hit test for translated child into translated box
* Add hit test for `FractionalTranslation`
* Don't check if RenderFractionalTranslation is hit themself
* Add hit test for FractionalTranslation
* Add test for FractionalTranslation
This fixes a runtime error triggered when calling `invokeRpc`:
```
type 'Future<dynamic>' is not a subtype of type 'Future<Map<String, dynamic>>'
```
Also adds a log message for why connections are failing, as well as a
default timeout when attempting to connect to a websocket.
This optimizes the AnimatedSwitcher so that it tags the right widget with its keyed subtree, and avoids rebuilding the transition unnecessarily.
This significantly improves the performance of Chips (which uses AnimatedSwitcher to swap out it's avatar and delete icon children).
