Fields used in Dart test with `@Native` fields must be `extern "C"` to
avoid name mangling.
As seen from build and test failures, MSVC doesn't seem to consistently
use C fields for `extern "C"` fields defined in a C++ file.
By moving these fields into a C file, they can be referenced both from
the other C++ test functions and via Dart fields.

Allow annotating top-level or static fields with `@Native` to create
fields backed by native memory.
By using the `_addressOf` operator implemented in the VM, these fields
can be implemented in the CFE by replacing them with accessors looking
up the pointer and then using existing methods to load and store the
value.

Enables passing inner pointers to typed data in FFI leaf calls.
This works for typed data's in the Dart heap, external typed datas
(constructed from `Pointer.asTypedList`), and typed data views.
Notable implementation details:
1. The Dart signature is used in the Marshaller now. This means it
needs to keep track of whether there's a pointer argument in the
signature (`asFunction`) or not (`@Native`).
2. Unwrapping is done in `FfiCallInstr::EmitNativeCode` before moving
the arguments to their native location. This ensures we can use
the assembler logic to load the `TypedDataBase::data` field.
3. The `XXXList` user visible classes don't have predefined cids.
So the implementation uses symbols for comparison.
4. The type checking logic takes `isLeaf` as input to reject typed
data. This leads to an error message about the type not accepted.
Alternatively, we could consider adding an error message that
specifically says the function should be leaf.
5. To cover all calling convention variants, tests are generated with
up to 20 arguments.

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.

We were exporting all symbols to the dynamic table so that they could be looked up using `dladdr` for the profiler and backtracer. The symbols include our statically-linked libcxx, which can create trouble when another DSO has a different version of libcxx. Now we export only the VM embedding API functions (`Dart_*`) and use a specially produced table to do the symbolization.

Creation of AppJit snapshot will not include the source of [Script]
objects (see `UntaggedScript::snapshot_to`). As a result there's no
point in letting the CFE embed the sources into the kernel if we
only use it to create an AppJit snapshot.
This is also in line with build rules for our dart-sdk, where we do the
kernel compilation separately, see utils/application_snapshot.gni:
```
template("application_snapshot") {
...
# Build the kernel file using the prebuilt VM to speed up the
# debug and simulator builds.
prebuilt_dart_action(target_name + "_dill") {
...
args = [
...
"--no-embed-sources",
...
]
[[[

...
