Summary: Update StackFrame::GetSymbolContext to mirror the logic in RegisterContextLLDB::InitializeNonZerothFrame that knows not to do the pc decrement when the given frame is a signal trap handler frame or the parent of one, because the pc may not follow a call in these frames. Accomplish this by adding a behaves_like_zeroth_frame field to lldb_private::StackFrame, set to true for the zeroth frame, for signal handler frames, and for parents of signal handler frames. Also add logic to propagate the signal handler flag from UnwindPlan to the FrameType on the RegisterContextLLDB it generates, and factor out a helper to resolve symbol and address range for an Address now that we need to invoke it in four places.
