[Python] Create StructArray from sequence of tuples given a known data type #18050
Description
Following ARROW-1705, we should support calling pa.array with a sequence of tuples, presuming a struct type is passed for the type parameter.
We also probably want to disallow mixed inputs, e.g. a sequence of both dicts and tuples. The user should use only one idiom at a time.
