[vm/ffi] Unwrap typed data in FFI calls

Enables passing inner pointers to typed data in FFI leaf calls.

This works for typed data's in the Dart heap, external typed datas
(constructed from `Pointer.asTypedList`), and typed data views.

Notable implementation details:
1. The Dart signature is used in the Marshaller now. This means it
   needs to keep track of whether there's a pointer argument in the
   signature (`asFunction`) or not (`@Native`).
2. Unwrapping is done in `FfiCallInstr::EmitNativeCode` before moving
   the arguments to their native location. This ensures we can use
   the assembler logic to load the `TypedDataBase::data` field.
3. The `XXXList` user visible classes don't have predefined cids.
   So the implementation uses symbols for comparison.
4. The type checking logic takes `isLeaf` as input to reject typed
   data. This leads to an error message about the type not accepted.
   Alternatively, we could consider adding an error message that
   specifically says the function should be leaf.
5. To cover all calling convention variants, tests are generated with
   up to 20 arguments.
