Subject: [PATCH] [lldb] Check for abstract methods implementation in Scripted
Plugin Objects
This patch enforces that every scripted object implements all the
necessary abstract methods.
Every scripted affordance language interface can implement a list of
abstract methods name that checked when the object is instanciated.
Since some scripting affordances implementations can be derived from
template base classes, we can't check the object dictionary since it
will contain the definition of the base class, so instead, this checks
the scripting class dictionary.
Previously, for the various python interfaces, we used `ABC.abstractmethod`
decorators but this is too language specific and doesn't work for
scripting affordances that are not derived from template base classes
(i.e OperatingSystem, ScriptedThreadPlan, ...), so this patch provides
generic/language-agnostic checks for every scripted affordance.
