REGR: make_block should still handle 1D DatetimeTZ data for 2D block

[jorisvandenbossche]

Caused by #41082, the following now fails:

In [1]: dtidx = pd.date_range("2012", periods=3, tz="UTC")

In [2]: pd.core.internals.make_block(dtidx, placement=[0])
...
ValueError: Wrong number of dimensions. values.ndim != ndim [1 != 2]

Even though the Block is now stored as 2D values, in our internal "public" API, we should still accept 1D values for datetimetz.

From the dask tests, dask/dask#7607
