[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.
