This patch changes the way frames created from scripted affordances like
Scripted Threads are displayed. Currently, they're marked artificial
which is used usually for compiler generated frames.
This patch changes that behaviour by introducing a new synthetic
StackFrame kind and moves 'artificial' to be a distinct StackFrame
attribut.
On top of making these frames less confusing, this allows us to know
when a frame was created from a scripted affordance.

This PR removes the `target-aarch64` requirement on the crashlog tests
to exercice them on Intel bots and make image loading single-threaded
temporarily while implementing a fix for a deadlock issue when loading
the images in parallel.

(#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.

This patch changes app_specific_backtrace_crashlog.test's crashlog file
extension from `ips` to `txt. This should prevent the test from opening
Console.app when being run.
This should also fix a test failure caused by missing symbols.

This patch fixes app_specific_backtrace_crashlog.test.
It was failing because one of the loaded images was built with
optimization which added a new warning message between the first
`CHECK` and the `CHECK-NEXT`, breaking the expected ordering.

For an exception crashlog, the thread backtraces aren't usually very helpful
and instead, developpers look at the "Application Specific Backtrace" that
was generated by `objc_exception_throw`.
LLDB could already parse and symbolicate these Application Specific Backtraces
for regular textual-based crashlog, so this patch adds support to parse them
in JSON crashlogs, and materialize them a HistoryThread extending the
crashed ScriptedThread.
This patch also includes the Application Specific Information messages
as part of the process extended crash information log. To do so, the
ScriptedProcess Python interface has a new GetMetadata method that
returns an arbitrary dictionary with data related to the process.
