[nullability] Fix `ParenTypeInTemplate` test. Before, it was using `targetNullable()` and `targetNonnull()` as function names, but we only analyze functions called `target()`. Framework change [#66197](https://github.com/llvm/llvm-project/pull/66197) fixes this so that we error out if there is no function called `target()`. This patch renames the functions to `target()` and additionally splits the test apart so there is only one call to `checkDiagnostics()` in each test (which makes it easier to understand what is going on if a test fails). Unfortunately, it turns out that we've regressed on two lines in `ParenTypeInTemplate3` while the test was not testing anything.

Crubit is an experimental 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.)
