  Log Message:
  -----------
  [lldb] Introduce SBFrameList for lazy frame iteration (#166651)

This patch introduces `SBFrameList`, a new SBAPI class that allows
iterating over stack frames lazily without calling
`SBThread::GetFrameAtIndex` in a loop.

The new `SBThread::GetFrames()` method returns an `SBFrameList` that
supports Python iteration (`for frame in frame_list:`), indexing
(`frame_list[0]`, `frame_list[-1]`), and length queries (`len()`).

The implementation uses `StackFrameListSP` as the opaque pointer,
sharing the thread's underlying frame list to ensure frames are
materialized on-demand.

This is particularly useful for ScriptedFrameProviders, where user
scripts will be to iterate, filter, and replace frames lazily without
materializing the entire stack upfront.
