[VM] Add automatic detection of timers that are significantly overdue This change makes it so that when the VM detects that a timer is at least 100 ms overdue, it sends a warning in a VM Service event on the 'Timer' stream. TEST=Built an Android Flutter app with a modified Engine that contained a `sleep` call in `eventhandler_linux.cc` and confirmed that the warning event got sent, built an iOS Flutter app with a modified Engine that contained a `sleep` call in `eventhandler_macos.cc` and verified that the warning event got sent, pkg/vm_service/test/overdue_timer_detection_test CoreLibraryReviewExempt: This CL does not include any core library API changes, only VM Service implementation changes.

Dart is:
Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.
Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
Dart is free and open source.
See LICENSE and PATENT_GRANT.
