PERF: avoid exceptions in string.Construction benchmark setup

[ngoldbaum]

#37371 added some new benchmarks, along with some new setup code for the new benchmarks. Unfortunately, the new setup code introduced an uncaught exception:

>>> import pandas._testing as tm
>>> from pandas import Categorical
>>> series_arr = tm.rands_array(nchars=10, size=10**5)
>>> frame_arr = series_arr.reshape((50_000, 2)).copy()
>>> frame_cat_arr = Categorical(frame_arr)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/nathan/Documents/pandas/pandas/core/arrays/categorical.py", line 399, in __init__
    raise NotImplementedError(
NotImplementedError: > 1 ndim Categorical are not supported at this time

This caused asv to skip all the string construction benchmarks since that PR was merged because the setup had an uncaught exception. See e.g. this benchmark report.

The fix is just to remove the broken benchmarks.

I built a version of pandas from just after #37371 was merged and verified that the benchmark was broken then. I can't easily verify that the benchmark has been broken the entire time since then but I strongly suspect that's the case.

Nice catch! I think ASV will skip benchmarks if the setup raised a NotImplementedError
