This patch adds support for arm64(e) targets to ScriptedProcess, by providing the `DynamicRegisterInfo` to the base `lldb.ScriptedThread` class. This allows create and debugging ScriptedProcess on Apple Silicon hardware as well as Apple mobile devices. It also replace the C++ asserts on `ScriptedThread::GetDynamicRegisterInfo` by some error logging, re-enables `TestScriptedProcess` for arm64 Darwin platforms and adds a new invalid Scripted Thread test. rdar://85892451 Differential Revision: https://reviews.llvm.org/D114923 Signed-off-by: Med Ismail Bennani <medismail.bennani@gmail.com>
