Remove _copy_construct factory

[vyasr]

This PR removes the _copy_construct factory method for the Frame types that were still exposing it, replacing its usage with _from_data. The current implementation of _from_data is slightly faster, and more importantly this change leaves us with a single fast path for building Frame objects (bypassing the slow constructors) so that we only have to maintain and optimize one going forward.
