This reverts commit 2d4c606e63.
The fix for the debug buildbot breakage now consists of skipping wide to utf8 conversion
altogether, instead move uri to path conversion directly into newly added File::OpenUri method.

The content handlers on Fuchsia can potentially give each Isolate
different handles to use for stdout and stderr. This change provides
a hook for an embedder to call to supply the handles to Dart, and
removes hardcoding of stdio handles to 0, 1, 2.

We were opening the untransformed path, which bypasses the namespace.
The other platforms appear to correctly use the transformed path in
their analogous code.

These were left out of order by the mechanical changes that were part
of Fuchsia's Magenta->Zircon rename.

Fuchsia requires the ability to sandbox Isolates w.r.t. file IO.
When a new Isolate starts, Fuchsia will pass the Isolate an object
called a namespace. We can translate the namespace object into a
file descriptor suitable for passing to the *at() family of
POSIX file system calls. The file system calls will then
have visibility only into the specified namespace.
We also plumb Namespaces through on all the other platforms as well to
make the change easier to test and so that in the future we can
implement e.g. per-isolate cwds.
This change adds a new internal class to dart:io called _Namespace,
which is implemented in a patch file. See:
sdk/lib/io/namespace_impl.dart
runtime/bin/namespace_patch.dart
The embedder can set up a non-default namespace by calling
_Namespace._setupNamespace during Isolate setup.
Instances of _Namespace have a native field that holds a pointer
to a native Namespace object. See:
runtime/bin/namespace.h
Calls from e.g. file_impl.dart are now also passed a
_Namespace object. The implementations in e.g. file.cc and
file_linux.cc then extract the namespace, and use it to compute a
file descriptor and path suitable for passing to e.g. openat().

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.

This CL changes File::Write on Windows to call directly to WriteFile()
instead of using _write(). This avoids a number of complexities:
1. Don't need to bother with text vs. binary mode.
2. Don't need to check both errno and GetLastError if _write() fails.
3. Don't need to convert to a wchar_t* for console output since we've
already set the code page to UTF8.

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.

This change has two pieces.
- Set the console code page to UTF8.
- This makes strings printed with print() display correctly
- Set the file translation mode to _O_WTEXT when writing to a
stdout or stderr that is connected to a console.
- This makes strings printed with e.g. stdout.writeln()
display correctly.

For blobs, put all four pieces into a single file with a header describing their offsets.
For dynamic libraries, move the vm isolate and isolate pieces into the dynamic library as additional read-only sections.
Automatically detect if the script argument is an app snapshot and initialize the VM appropriately, similar to automatic detection of script snapshots.

This CL adds targets to the GN build that build the standalone Dart VM
without the observatory, and with dart:io enabled but with most of the
functionality stubbed out as UNIMPLEMENTED(). It also adds a simple
eventhandler for Fuchsia for implementing Timers.
