- Mark dynamic_load_test as failing in the reload stress tests (reload fails to preserve library identity).

In addition, this removes support for seeding the VM isolate snapshot with Instructions and referencing those Instructions in the isolate snapshot. This was leftover from an earlier experiment to share Instructions between a Core-JIT snapshot and App-JIT snapshots. Removing this reclaims the sign bit on Instruction offsets.

Dart_LoadKernel is only used in Flutter engine and dart_runner, where it is always used as Dart_LoadKernel(Dart_ReadKernelBinary). These uses should be replaced with Dart_LoadScriptFromKernel.
Dart_LoadLibraryFromKernel is needed for loading split kernel files and implementing IsolateMirror.loadUri.

The only fix needed for relanding is adding _ensureScheduleImmediate
to the list of vm entrypoints in //runtime/vm/compiler/aot/precompiler.cc
Original commit message:
Adds a top-level call waitForEventSync to dart:io that blocks the
thread an Isolate is running on until messages are available.
Before the thread blocks, the microtask queue is drained.
Before waitForEventSync returns, all messages are handled.
Lifting this up from a comment:
This is apropos of the request that nweiz@ sent to the mailing list a
couple weeks back. I'm not sure we should land this. We certainly
shouldn't land it without some annotations that will make the analyzer
complain a lot in most configurations, but I don't know what those
annotations are.

Currently, we have some tests that run with reified generic functions ON and
some with it OFF. However, this causes inconsistencies when running the Kernel
FE from snapshot in the VM, since the VM requires that the flag be consistent
with the snapshot. Our solution is to turn the reified generic functions flag
into a per-isolate flag, which is always disabled in the Kernel FE's isolate.

Includes the following changes:
- Disable type checking in the service isolate when strong mode is
turned on. We don't yet have strong mode clean vmservice Kernel
binary available (Issue #31203);
- Introduce new Dart VM API to allow creating List<T> (T in {String, int}).
Current API only allows to create List<dynamic> and in strong mode
List<dynamic> is not assignable to List<T>. For now we limit this API to
a fixed number of core types for performance considerations (type
arguments can be canonicalized and cache ahead of time). We will
extend the API allowing creation of arbitrary List<T> if we will
discover the need for it later;
- Use this new API to fix CreateRuntimeOptions to create List<String>
and not List<dynamic>;
- Likewise fix OneByteString_splitWithCharCode to return List<String>
and not List<dynamic>;
Additionally this CL refactors how getters and setters are created
in object_store.h removing 500 lines of largely boilerplate code.
