[vm/ffi] Allow omitting native types for `@Native` functions

This change simplifies working with `@Native`-annotated functions by allowing the native type to be omitted when it can be inferred from the Dart function's signature. While this was previously supported for `@Native` fields, it now applies to functions as well.

Before this change, you needed to specify the native type explicitly:
```
@Native<Void Function(Pointer)>()
external void free(Pointer p);
```

After this change, the native type can now be omitted if it's clear from the Dart signature:
```
@Native()
external void free(Pointer p);
```
