[gardening] Use a read lock instead of a write lock When accessing the list of isolates in a group to get the first one we only need a read-lock, not a write-lock. This fixes hot-reload bot timeouts where a mutator hits a StackOverflow slowpath that triggers a reload, which loops over all isolates in a group to stop BG compiler (takes read lock). The BG compiler in return will try to acquire write-lock for `FirstIsolate()`, which causes a deadlock. TEST=Existing reload timeouts.

Dart is:
Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.
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.
