asv tests for DataFrame constructor

[toobaz]

After #18769 , the asv coverage of different possibilities of initialization values for Series() should be pretty good (see asv_bench/benchmarks/ctors.py ).

The coverage for DataFrame instead (see asv_bench/benchmarks/frame_ctor.py) is more limited and should be expanded.

Hello, I am a first-time contributor. If this issue is still open would it be okay for me to work on this?
