[test/ffi] Structs by value 1-byte aligned

The 3 and 7 byte tests in
had their sizes rounded up to the next power of two due to alignment of
fields inside the structs.

In order to properly exercise behavior on win32, win64 and iOS, this CL
changes those structs to only have uint8 fields to prevent alignment
influencing the sizes.

Old tests are renamed to exercise the size rounding due to alignment.

This also swaps around the two 9byte structs to have consistent naming
with the new 3 and 7-byte tests.

structs_by_value_tests_confguration.dart is the only non-generated file.

The tests are tested in the dependent CL. Tests are ignored in status
file and are un-ignored in dependent CL.

Tests for https://github.com/dart-lang/sdk/issues/36730.

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
