[lldb/plugins] Add arm64(e) support to ScriptedProcess

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.
