Split off https://dart-review.googlesource.com/c/sdk/+/140290 to make that CL smaller. This CL adds support for passing struct arguments in the native calling convention calculation in `runtime/vm/compiler/ffi/native_calling_convention.cc`. The code in this CL is unit tested with expect files. The unit tests are designed to cover the majority of corner cases in the ABIs without resorting to very many unit tests. TEST=runtime/vm/compiler/ffi/native_calling_convention_test.cc The code in this CL has been end-to-end tested in the CL it is split off from. And will be end-to-end tested when that CL also lands.
