Michael Buch 54896838ca [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.
