Introduce the concept of internal stop hooks. These are similar to LLDB's internal breakpoints: LLDB itself will add them and users of LLDB will not be able to add or remove them. This change adds the following 3 independently-useful concepts: * Maintain a list of internal stop hooks that will be populated by LLDB and cannot be added to or removed from by users. They are managed in a separate list in `Target::m_internal_stop_hooks`. * `StopHookKind:CodeBased` and `StopHookCoded` represent a stop hook defined by a C++ code callback (instead of command line expressions or a Python class). * Stop hooks that do not print any output can now also suppress the printing of their header and description when they are hit via `StopHook::GetSuppressOutput`. Combining these 3 concepts we can model "internal stop hooks" which serve the same function as LLDB's internal breakpoints: executing built-in, LLDB-defined behavior, leveraging the existing mechanism of stop hooks. This change also simplifies `Target::RunStopHooks`. We already have to materialize a new list for combining internal and user stop hooks. Filter and only add active hooks to this list to avoid the need for "isActive?" checks later on.
