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 patch addresses 2 issues:
1. It makes registers available on non-crashed threads all the time
2. It fixes arm64 registers parsing for registers that don't use the `x`
prefix (`fp` -> `x29` / `lr` -> `x30`)

This patch makes interactive mode as the default when using the crashlog
command. It replaces the existing `-i|--interactive` flag with a new
`-m|--mode` option, that can either be `interactive` or `batch`.

By default, when the option is not explicitely set by the user, the
interactive mode is selected, however, lldb will fallback to batch mode
if the command interpreter is not interactive or if stdout is not a tty.

This also adds some railguards to prevent users from using interactive
only options with the batch mode and updates the tests accordingly.

Remove lldb-repro which was used to run the test suite against a
reproducer. The corresponding functionality has been removed from LLDB
so there's no need for the tool anymore.

Reverts llvm/llvm-project#94575 since introduces test failure:

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.

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.

In lldb, users can change the `dsymForUUID` binary using the
`LLDB_APPLE_DSYMFORUUID_EXECUTABLE` environment variable.

This patch changes the crashlog to support the same behaviour as lldb
and uses this environment variable to disable `dsymForUUID` lookups in
crashlog test by having it be empty. Since CI bots shoudn't have access
to images on build records, it doesn't make sense to make use of
`dsymForUUID` in tests.
