This enables other emdedders to reuse parts of the standalone embedder
implementation without depending too much on the implementations details.
As part of the change we also remove a dependency from DartUtils on
IsolateData - by removing dart:_builtin library caching. Lookup
of this library does not seem to be on hot path anymore in Kernel world.

- Fix for 'unable to read .packages file' error when generating
kernel file (script snapshot).
- Make sync-async an isolate specific flag and turn it off for
the kernel isolate as it runs in Dart 1 mode
- Include 'reify-generic-functions' and 'sync-async' flags to the
list of flags to check an app JIT snapshot against.

This change, and the code introduced, is probably not going to be required
once the platform kernel file is linked into the executable.

Do not rely on the udp_receive_buffer field from IsolateData as a buffer for
reading data in the recvfrom call.

2. Read the platform dill file at startup not for every isolate creation
3. Store the memory representation of kernel program in isolate data so that it is deleted when the isolate is shutdown

IsolateData contains AppSnapshot which might own some HeapPage-s, so we can't
destroy IsolateData in the Dart_IsolateShutdownCallback, because some thread
running in the isolate (e.g. background compiler) might still touch
thoses pages or objects they host.
We need to delay destruction of AppSnapshot until after the isolate shutdown.
Current API does not allow that, so we introduce a new isolate lifecycle
callback - Dart_IsolateCleanupCallback, which is invoked at the end of the
isolote lifecycle when things like background compiler have been stopped
and no Dart code is supposed to run.

This lets us remove a hack from the PRESUBMIT.py script that existed
for reasons that are no longer valid, and sets us up to add some
presubmit checks for the GN build.

- Arbitrary number of native and Dart arguments can be attached to each event
- JSON printing
- Output can be loaded by about://tracing

Initial implementation of UDP support in dart:io
Added a RawDatagramSocket which gets the same events as a RawSocket
except that READ_CLOSED is never received.
The receive from a RawDatagramSocket returns a Datagram object where
the senders address and port is presten together with the data.
The send on a RawDatagramSocket takes data and the address and port of
the destination.
Extended the number of socket options to support UDP.
Added getting the socket options.
