Support for Apple silicon

[dkocher]

Dependent on java-native-access/jna#1238

[ccidral]

@dkocher Just curious, were you able to build and use rococoa under Apple silicon? I see that java-native-access/jna#1238 has been closed.

There are several things to be sorted out

• Make sure JNA has no test failures on Apple silicon. See #1323
• Always use objc_msgSend on Apple silicon to be patched in MsgSendHandler
• Fix several test failures in Rococoa possibly caused by not type safe calling objc_msgSend .

To fix dynamic-dispatching issues in your code, define a type-safe function pointer instead of calling objc_msgSend directly. Refer to Enable Strict Type Enforcement for Dynamic Method Dispatching

Not sure if this is actually an issue with JNA using libffi.

We are making progress.
