Joyee Cheung 0ea5b5248d [class] implement inspector support for static private methods
When looking for private members in an object for the inspector,
we check if that object is a class constructor with the a bit
has_static_private_methods set on its SFI. If it
is, we look for any variables in the context locals
with a VariableMode associated with private methods or accessors
and a IsStaticFlag being kStatic.

This patch also filters out static private methods when inspecting
instances.
