Daco Harkes 1755f89092 [vm/ffi] Add class modifiers ... Adds class modifiers to `dart:ffi`. Migrates all user-defined subclasses of `Struct`, `Union`, `Opaque`, and `AbiSpecificInteger` to be `final class`es. Does not remove the manual error checking, so some errors will show up twice now in language version 3.0. In language version <3.0, only the FFI-specific error will show up. In a follow-up CL, we will try to make the language-errors to show up also <3.0 so that we can remove the FFI-specific errors. Examples of duplicated errors: pkg/analyzer/test/src/diagnostics/subtype_of_ffi_class_test.dart TEST=pkg/analyzer/test/ (for the analyzer) TEST=pkg/front_end/testcases/ (for the CFE) TEST=test/ffi/ (for the VM) CoreLibraryReviewExempt: No need for dart2js to review.
