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.

There is no actual implementation here yet (that's your job :) ), but there is:
- An external method in dart:_internal, extractTypeArguments().
- Empty patch methods for that for the VM, dart2js, and DDC. These need to have implementations
filled in.
- A "dart_internal" package to expose a subset of the API. It gives you:
extractListTypeArgument()
extractMapTypeArguments()
We'll bring this into Google, but not publish it externally unless we find we really need to.
- A test for the behavior. It probably has bugs since I can't run it.

This is a strong mode migration that was missed in the earlier rounds.
It allows use of functions that have a more restricted argument type than Object in strong mode
while still ensuring that the argument has a correct type.

This should improve performance of these members in most cases:
- toString
- operator ==
- hashCode
- runtimeType
- noSuchMethod
The helpers for checking `null` and then dispatching to the method are now very small again. Also, because we can lookup symbolized names always, we can start taking advantage of this in our Map/Set implementations (for a follow up CL).
This also improves correctness of these helpers given JavaScript objects; we were previously falling back to calling a Dart method name like `.hashCode`, which is incorrect (except for `toString` where fallback is probably the correct behavior).

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().

- optimize interface checks for some dart:core and dart:async types (List, Map, Iterable, Future, Stream, and StreamSubscription )
- optimize checks for generic class default instantiations and exact instantiation (e.g. `C<dynamic>` on any instance `C<T>`, and `C<T> on an instance of C<T>`
- optimize checks for native types
- optimize getReifiedType
- optimize dcall/dsend/dput checks to use faster Type._check pattern
- optimize instanceOf/cast functions by moving special cases to appropriate types
- optimize Object.runtimeType
- optimize JS interop type checks
- optimize all function type checks

Eliminate numerous type checks not needed in strong mode. Use
private nullability annotations instead of inline JS to mark known
non-null variables, and to make the compiler generate null checks
for null checked variables. Use nullability annotations and code refactoring to
remove redundant null checks and to move checks out of loops.

Previously, the string set up by the embedder was eagerly passed to
Uri.parse during Isolate startup. This is expensive both in time and
memory footprint. This CL causes Uri.parse() to be called only
when needed. This change will allow reducing the memory footprint
of Fuchsia's Dart content handler on hello world by ~1MB.
