[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.

[lldb/crashlog] Add `--no-parallel-image-loading` hidden flag (#94513)

This patch adds the `--no-parallel-image-loading` to the crashlog
command. By default, image loading will happen in parallel in the
crashlog script however, sometimes, when running tests or debugging the
crashlog script itself, it's better to load the images sequentially.

As its name suggests, this flag will disable the default image loading
behaviour to load all the images sequencially in the main thread.

[lldb/crashlog] Enforce image loading policy (#91109)

In `27f27d1`, we changed the image loading logic to conform to the
various options (`-a|--load-all` & `-c|--crashed-only`) and loaded them
concurrently.

However, instead of the subset of images that matched the user option,
the thread pool would always run on all the crashlog images, causing
them to be all loaded in the target everytime.

This matches the `-a|--load-all` option behaviour but depending on the
report, it can cause lldb to load thousands of images, which can take a
very long time if the images are downloaded over the network.

This patch fixes that issue by keeping a list of `images_to_load` based
of
the user-provided option. This list will be used with our executor
thread pool to load the images according to the user selection, and
reinstates
the expected default behaviour, by only loading the crashed thread
images and
skipping all the others.

This patch also unifies the way we load images into a single method
that's shared by both the batch mode & the interactive scripted process.
