11b9466c - [lldb] Add ability to inspect backing threads with `thread info` (#129275)

[lldb] Add ability to inspect backing threads with `thread info` (#129275) When OS plugins are present, it can be helpful to query information about the backing thread behind an OS thread, if it exists. There is no mechanism to do so prior to this commit. As a first step, this commit enhances `thread info` with a `--backing-thread` flag, causing the command to use the backing thread of the selected thread, if it exists.
