This change is to reduce memory usage and maximum minor GC time for Flutter and Fuchsia.
It would negatively impact batch applications, which prefer throughput,
so the new defaults are overriden by the command-line Dart VM in

The `@pragma` annotation on `vmservice_io.main` is modified to only mark it as a
root on non-product builds. Since the annotation is evaluated in the constant
transformation, we need to thread a flag through `gen_kernel.dart` indicating
whether the Kernel produced should target a product precompiler.
# Test Plan
Tested locally on Flutter. Unfortunately it's not possible to test the scenario where
`vmservice_io` is not included, since we don't have any "product" bots. Soon the
flag will be introduced into Flutter, and we will have some coverage from there.

The isolate creation callback flow was using DFE::kernel_file_specified()
to decide whether to load kernel program or not. However, since this flag
is not isolate specific, it was causing problems in the case where a dill
file was passed as the main dart program; the other isolates, even if
they were loading a snapshot, were looking for a kernel program.
This change was originally submitted as
"Make the decision, on whether to start the kernel isolate, liberal." It
was reverted due to failures on simdbc bots. This change is another
attempt which fixes those failures.
