[lldb/crashlog] Always load Application Specific Backtrace Thread images (#94259)

This patch changes the crashlog image loading default behaviour to not
only load images from the crashed thread but also for the application
specific backtrace thread.

This patch also move the Application Specific Backtrace / Last Exception
Backtrace tag from the thread queue field to the thread name.
