dd060bde - [lldb] Add frame recognizers for libc++ `std::invoke` (#105695)

[lldb] Add frame recognizers for libc++ `std::invoke` (#105695) With this commit, we also hide the implementation details of `std::invoke`. To do so, the `LibCXXFrameRecognizer` got a couple more regular expressions. The regular expression passed into `AddRecognizer` became problematic, as it was evaluated on the demangled name. Those names also included result types for C++ symbols. For `std::__invoke` the return type is a huge `decltype(...)`, making the regular expresison really hard to write. Instead, I added support to `AddRecognizer` for matching on the demangled names without result type and argument types. By hiding the implementation details of `invoke`, also the back traces for `std::function` become even nicer, because `std::function` is using `__invoke` internally.
