This CL implements unaligned access for float/double on arm32, but does
not expose it in an API. Rather it only uses these loads/stores inside
the getters and setters of packed structs.
Bug: https://github.com/dart-lang/sdk/issues/45009
Besides unaligned access for float/double, this CL is mostly a CFE
change. The only VM change is reading the packing in the
`_FfiStructLayout` annotation.
The implementation of using the packing in the VM, and analyzer changes
have landed separately in earlier CLs.

This CL adds support for nested structs in FFI calls, callbacks, and
memory loads and stores through the Struct classes itself.
Nesting empty structs and nesting a structs in themselves (directly or
indirectly) is reported as error.
This feature is almost fully implemented in the CFE transformation.
Because structs depend on the sizes of their nested structs, the structs
now need to be processed in topological order.
Field access to nested structs branches at runtime on making a derived
Pointer if the backing memory of the outer struct was a Pointer or
making a TypedDataView if the backing memory of the outer struct was
a TypedData.
Assigning to a nested struct is a byte for byte copy from the source.
The only changes in the VM are contained in the native calling
convention calculation which now recursively needs to reason about
fundamental types instead of just 1 struct deep.
Because of the amount of corner cases in the calling conventions that
need to be covered, the tests are generated, rather than hand-written.
ABIs tested on CQ: x64 (Linux, MacOS, Windows), ia32 (Linux, Windows),
arm (Android softFP, Linux hardFP), arm64 Android.
ABIs tested locally through Flutter: arm64 iOS.
ABIs not tested: ia32 Android (emulator), x64 iOS (simulator), arm iOS.

Sign extension of small integers is not symmetric between register arguments and register return values.
On Linux/MacOS x64, the caller is responsible for both the arguments and return value.
Previous tests only tested equality, which tests the equality of the lowest byte. However, when printing or using the small ints arithmetic all 4 bytes are used. The new tests pass back the number in a different format.
The callback tests test the number in Dart, so they did not suffer from implicit conversions. (TestTakeMaxUint8x10 in runtime/bin/ffi_test/ffi_test_functions.cc and tests/ffi_2/function_callbacks_test.dart.)

The `tests/ffi/prepare_flutter_bundle.dart` script will try to discover
all synchronous, positive test from the "ffi" test suite, rewrite them
slightly and output a directory which can be used in a flutter/flutter
FFI integration test.
We split the ffi test functions into two parts, because a subset of the
C functions will issue calls to the VM via `dart_api.h`, which is not
available for the flutter/flutter integration test.
=> We make `runtime/bin/ffi_test/ffi_test_functions.cc` a pure C
library, usable without `dart_api.h` and move the remaining VM
specific code to .../ffi_test_functions_special.cc contains.
All tests from `tests/ffi/*_test.dart` will be included in the generated
bundle, which
* don't use async/isolates
* don't rely on VM api
* don't rely on DynamicLibrary.{process,executable}
* don't take too long to execute
The script can be used as follows:
sdk % dart tests/ffi/prepare_flutter_bundle.dart foo
Using SDK root: .../sdk
The following tests will be included:
