call_annotate_function

Call an __annotate__ function. __annotate__ functions are normally
generated by the compiler to defer the evaluation of annotations. They
can be called with any of the format arguments in the Format enum, but
compiler-generated __annotate__ functions only support the VALUE format.
This function provides additional functionality to call __annotate__
functions with the FORWARDREF and STRING formats.

*annotate* must be an __annotate__ function, which takes a single argument
and returns a dict of annotations.

*format* must be a member of the Format enum or one of the corresponding
integer values.

*owner* can be the object that owns the annotations (i.e., the module,
class, or function that the __annotate__ function derives from). With the
FORWARDREF format, it is used to provide better evaluation capabilities
on the generated ForwardRef objects.
