Preliminary testing shows, this increases performance by around 20%. The
main benefit is by re-using a warmed-up VM and not start one from
scratch for every compilation.
Going forward we can do more optimizations, e.g. reading the platform
dill file only once into memory (instead of repeatedly) ...
=> This requires us using the new state-full IKG compiler.

Switch it to use pkg/vm/tool/dart2 which is the source of truth for what
Dart 2 VM configuration means. Don't pass any additional flags from
tools/test.py itself.
Align pkg/vm/tool/dart2 with what tools/test.py was passing to VM on _2 suites.
Make default invocation `tools/test.py -c dartk --strong -m release,debug`
green by updating status files and skipping suites that are not Dart 2.0
compliant. I have filed issues #31588 for isolate suite and #31587 for
service suite.

This CL deprecates the front-end API and moves it into src/api_prototype.
For now all usages have been updated to point to the new location,
but they should be updated to use custom-client invocations instead (e.g.
one specific way for DDC, another for dart2js etc.)

This CL introduces compileToKernel() function in package:vm/kernel_front_end
as the replacement for kernelForProgram() from package:front_end/kernel_generator.
The new function will be used to customize kernel Programs for VM need.
For example, it will perform additional AOT-specific global transformations.
In future, compileToKernel() will be used from Flutter and precompiler2.
Also, this CL cleans up Target.strongModeSdk as it is no longer used.

These wrapper scripts centralize the notion of what Dart 2 means for VM.
They enable relevant flags and use relevant intermediate code generation steps
where necessary.
* pkg/vm/tool/dart2 invokes dart binary with DFE and strong mode.
* pkg/vm/tool/precompiler2 uses Fasta and AOT specific Kernel-to-Kernel
transformations to generate Kernel binary which then will be compiled with
normal Dart VM precompiler.
* pkg/vm/tool/dart_precompiled_runtime2 is similar to dart2 wrapper but for running
AOT snapshots.
