Both thread and isolate have sticky error fields. Dart API was using
isolate's sticky error, while Dart code was using thread's sticky error.
There was a one-way move of a thread's sticky error into isolate
when thread was unscheduled.
This causes a problem as error in the isolate may go unnoticed and
repeated unscheduling/re-scheduling might end up overwriting the error
in the isolate (which triggers the assertion).
To solve this problem, this CL:
* Cleans up Dart API which manipulates isolate's sticky error, so
isolate's sticky error is never set directly.
* When sceduling an isolate to a thread, sticky error is moved back from
isolate (if any).
With this changes, thread's sticky error is always used if thread is running,
and isolate's sticky error is only used to hold sticky error while
isolate has no thread.

This allows developers to have more fine grained control over socket
options supported by their platforms, particularly when there is not a
nice way to encapsulate differences between IPv4 and IPv6 options (as
with IP_MULTICAST_IF and IPV6_MULTICAST_IF). It also begins the work
of exposing socket level and option values, although keeping it for now
only to a minimum necessary to assist with setting the multicast
interface for datagram sockets.
This CL also marks `multicastInterface` as deprecated.

Original PR was reverted because it broke hot-reload bots. This CL adds steps to initialize kernel_service compiler for child isolate. Compiler is needed to support hot-reload request. Child isolate's compiler is created from full kernel file produced by main isolate's compiler. Changes since original PR are pkg/vm/bin/kernel_service.dart in pkg/vm/lib/incremental_compiler.dart.
Further this CL changes kernel fingerprint calculation for interface types so it calculates the hash of the canonical names themselves, rather than indices(that might change from one compilation to another).
This reverts commit 63fd8f63e6.

We prevent our crashing tests from hitting timeouts on the bots
by disabling Windows Error Reporting UI via SetErrorMode.
However this also disables builtin crash dump generation functionality
that WER has.
This change moves WER suppression for GP faults under a flag to
make sure that we can collect crash dumps when VM crashes on
user machines.
We also make sure that our exception handler call abort()
instead of calling exit() - because exit would not cause
WER to generate a dump.

Currently the @pramga('vm:exact-result-type') annotation only works if
the function is a recognized method. This change changes that to make
the VM just look if a function has the annotation (no matter if it's
also in the list of recognized methods or not).
Furthermore this CL lets the type propgagator use
@pragma('vm:exact-result-type') annotations to narrow the [CompileType]
set on [LoadFieldInstr]s.
Since the @pragma is a general feature, this CL moves the
`Function::FindPragma()` to `Library::FindPragma` (which is where any
other metadata lookup happens). We also let the `FindPragma` accept any
of Class/Function/Field objects.
Furthermore the `FindPragma()` function is fixed to handle the case
when the evaluation of the metadata results in an error.
In this case we simply claim to not have found a pragma annotation.

binary that would handle the crash and write minidump;
- DART_CRASHPAD_CRASHES_DIR should contain the path to the crashpad database
