Merge `toolchain/check/testdata/interop/cpp/class/struct.carbon` into `class.carbon` (#6198)

The tests are almost identical and test the same logic so basically
duplicated.
The extra coverage that was in `struct.carbon` is added to
`class.carbon`.
One basic test in `struct.carbon` was left just to make sure `struct` is
supported.

Part of #5150.
