2914a4b888
This patch introduces a new `template` multiword sub-command to the `scripting` top-level command. As the name suggests, this sub-command operates on scripting templates, and currently has the ability to automatically discover the various scripting extensions that lldb supports. This was previously reviewed in #97273. Signed-off-by: Med Ismail Bennani <ismail@bennani.ma>
