Upstreamed changes from cl/579854752.
The cross-compiler checks some things that are check on Windows.
* Correct capitalization of filenames in includes.
* Field initialization order in constructors.
In the cross compilation process, some binaries are run on the host.
This unveiled missing `UnwindingRecords::GenerateRecordsInto`.
Finally, when emitting blob data with a symbol in assembly, the
`.type` directive is not supported but the format should still be
unix style assemble. So this CL introduces "win_gnu". This tool is
directly invoked from the build-rules in cl/579854752, and will not be
used until we address https://github.com/dart-lang/sdk/issues/28617.

Handle::data_ready_ contains bytes which are ready to be sent to Dart
side. Not all code paths fully drain this buffer and delete it
before destroying the handle, for example directory watch implementation
was prone to leaking data_ready_ when subscription was cancelled.
This CL switches the code to use unique_ptr to hold on to data_ready_
which makes sure that it is deleted when Handle is destroyed.
The code would benefit from holding all OverlappedBuffer instances
through unique_ptr but that is a much larger refactoring which
we leave for a later date.

This relands https://dart-review.googlesource.com/c/sdk/+/205633
but without renaming TARGET_OS_IPHONE to DART_TARGET_OS_IPHONE.
It also changes uses of TARGET_OS_IOS to
DART_TARGET_OS_MACOS_IOS to be consistent with the rest of the
VM.
TargetConditionals.h for XCode 13 defines several
TARGET_OS_* preprocessor symbols that confuse the
Dart build. There is probably a more targeted fix
for this, but renaming the symbols that Dart uses
will also prevent this problem if more symbols
are added to the platform headers in the future.

Crashes come from assertion in ReturnTokens() and new_mask() in Eventhandler.
Another issue is when multiple serversockets bind to the same address, Socket will be reused to all Dart_Ports. But Socket didn't keep track of corresponding Dart Port.
When one of isolates is killed, finalizer wakes up and close most recent Dart Port that sends data.
After this cl, Socket may not be reused by different Dart Sockets. All Dart socket will has its own Socket object. But Sockets can have same fd.
This will guarantee finalizer will close right Dart Port.

ClientSocket might have pending operations associated with it, so we should
not delete it until those operations fire.
This aligns ClientSocket::IsClosed with IsClosed implementation for other
handles, which check if handle has any associated pending operations.
The situation that sometimes arises it that if we issue Read, Disconnect operation,
they might complete in the opposite order DisconnectComplete, ReadComplete, which
is why we need to check for pending operations.
MSDN contains sentences like these: "Please note that while the packets are
queued in FIFO order they may be dequeued in a different order."
It seems that a more uniform fix would be to it increment a reference count
of a handle whenever an asynchronous operation is started and decrement it
whenever it is completed - but such fix requires much more thorough
refactoring of eventhandler_win.cc.

This is a reland of https://dart-review.googlesource.com/c/sdk/+/62484
with the following changes:
- _NativeSocket.connect now drops references to pending sockets on
an error or successful connection.
- eventhandlers are updated to ignore unset Dart ports on a close
command.
- Test updated to account for new SocketException.
This is the second part of https://dart-review.googlesource.com/c/sdk/+/62484
This CL adds a startConnect method to Socket types that returns
a ConnectionTask object that can be cancelled. Cancelling
a ConnectionTask closes any sockets that were opened for the
connection attempt that are not yet connected to the host.
This allows a closing HttpClient to close sockets for pending
requests whose sockets weren't fully connected yet.

If an Isolate touches the 'stdio' getter, a _NativeSocket with
attached finalizer is created for it. Previously, when such an
Isolate exited, the finalizer would close the underlying
file descriptor. This CL changes the finalizer for stdin such
that the native objects will be cleaned up, but the underlying
file descriptor will not be closed. The underlying file
descriptor will now only be closed if the stdin stream
subscription is explicitly canceled.
Accessing the stdin getter after the stream is explicitly
canceled will result in a FileSystemException.

The finalizer sends the "close" message to the EventHandler for the
file descriptor in the _NativeSocket's native field. To avoid races and
spurious messages, this CL stores a pointer to a wrapper object in the
native field instead of the file descriptor. All messsages about the
_NativeSocket sent to the EventHandler use the wrapper object instead of
the file descriptor. When the EventHandler closes the file, the file
descriptor in the wrapper object is set to -1 so that the finalizer will
instead do nothing.
On Windows, there is another level of indirection since the OS HANDLEs
were already wrapped in various kinds of Handle objects. As an additional
complication, ClientSocket close on Windows is asynchronous, so the
EventHandler may shutdown before all of the ClientSocket Handles can be
destroyed.

Like HOST_ARCH_*, HOST_OS_* describes the OS the VM is running on, which may be different from the OS the VM is generating code for during AOT compilation.
Currently we conflate the two when emitting AOT as assembly, and we get away with it because Flutter only uses assembly for targeting iOS and one can only target iOS from a Mac, but we expect to use assembly for Android as well so native tools can unwind Dart frames.

When cancelling a subscription to stdin, there may be pending I/O operation

These threads are polluting the exit code despite using the better
ExitProcess call. Instead of adding back Thread::Join, I've instead
inlined the call into the eventhandler to make it easier to be sure
the open handles are closed.

Also:
- Reaps exited threads in the thread pool before putting
a thread on the idle list so that a new arriving task
isn't blocked on a supposedly idle thread in the middle
of a join.
- Stops trying to join eventhandler threads on
Windows. Now that we're using the correct exit() call,
we probably don't have to worry about exit code pollution,
so joining the threads is unnecessary.

Previously we would compile in implementaitions of native calls for
IO functions that would never be used. This CL provides implementations
that throw a Dart exception if they're called by mistake. It also uses
a DART_IO_DISABLED preprocessor define to clean up the build files and
check that we're not including code we shouldn't.
