[gardening] Attempt to fix flakily timing out service{,_2}/get_vm_timeline_rpc_test We launch the subprocess with --complete-timeline which will collect and buffer all timeline events in-memory. This works ok if we don't have too many events and if we have enough memory. On ia32 in particular the JIT's kernel-service runs from kernel file (not from an app-jit trained snapshot). That means it's slow and possibly produces many more timeline events since kernel-service isolate has to JIT all of the CFE in order to compile the test script. On ia32 we only have 2 or 3 GB of memory available. So this could lead to OOMs to due the timeline buffer getting too large. (See issue below for more information) This is an attempt to fix that by first compiling the testee to kernel, so the subprocess can be run immediately from kernel instead of first needing to compile via CFE. Issue https://github.com/dart-lang/sdk/issues/43504 TEST=Tries to make flakily timing out less flaky.

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.
