39572f5e - [lldb][Target] Clear selected frame index after a StopInfo::PerformAction (#133078)

[lldb][Target] Clear selected frame index after a StopInfo::PerformAction (#133078) The motivation for this patch is that `StopInfo::GetSuggestedStackFrameIndex` would not take effect for `InstrumentationRuntimeStopInfo` (which we plan to implement in https://github.com/llvm/llvm-project/pull/133079). This was happening because the instrumentation runtime plugins would run utility expressions as part of the stop that would set the `m_selected_frame_idx`. This means `SelectMostRelevantFrame` was never called, and we would not be able to report the selected frame via the `StopInfo` object. This patch makes sure we clear the `m_selected_frame_idx` to allow `GetSuggestedStackFrameIndex` to take effect, regardless of what the frame recognizers choose to do.
