[nullability] Smart pointers: Use `thisPointerType` matcher instead of `on`. The `on` matcher would only match if the implicit object argument was a smart pointer glvalue (i.e. if the method was called with the syntax `.method()`, but not if it was a raw pointer to a smart pointer (i.e. if the method was called with the syntax `->method()`). This patch adds tests for the affected matchers that fail without the fix. The patch also adds an "integration test" that uses the `->method()` syntax in a test for the transfer function.

Crubit is a bidirectional bindings generator for C++ and Rust.
Please don‘t use, this is an experiment and we don’t yet know where will it take us. There will be breaking changes without warning. Unfortunately, we can't take contributions at this point.
Crubit allows for C++ code and Rust code to call each other without manually wrapping the APIs in an FFI-friendly interop layer. For example, a C++ function like this:
bool IsAbsPath(std::string_view path);
... becomes callable from Rust as if it were defined as:
pub fn IsAbsPath(path: std::string_view) -> bool {...}
Crubit automatically generates ABI-compatible bindings for structs (which can be passed both by value and by reference), functions, and methods, for a large variety of types. (Trivial types, nontrivial types, templated types, etc.)
