  [lldb] Skip the prologue before reading `this` when stepping into std::function (#209629)

Commit 40152b8 broke CPPLanguageRuntime::GetStepThroughTrampolinePlan by
changing operator() from a multi-line function to a single line
function.

This used to work by accident, because the fallback step-in plan first
advanced past the prologue and the trampoline detection was re-invoked
there with a valid `this`. Once operator() became a one-line inline
definition that intermediate step no longer happened.

Run past the prologue when stopped at the function entry and let the
step-through machinery re-invoke the plan, so the thread plan has a
valid `this` to read from.
