Hot reload UI polish (#5193)
* General improvoments to the loader app:
* Show a message after 8 seconds if no connection comes in.
* Show a progress bar as files are being uploaded.
* Hide the spinner just before launching the application.
* General improvements to the "flutter run" UI:
* Add "?" key as a silent alias for "h".
* Make the help text bold so it doesn't get mixed with the logs.
* Make "R" do a cold restart when hot reload is enabled.
* Supporting features and bug fixes:
* Add support for string service extensions.
* Other bug fixes:
* Expose debugDumpRenderTree() outside debug mode.
* Logger.supportsColor was missing a getter.
* Mention in the usage docs that --hot requires --resident.
* Trivial style fixes.
