Fix numerical functions that can only use numeric inputs (var, skew, mean but not max, min)

[williamma12]

Describe the problem

Uses only numeric values even when numeric_only=False. We should be consistent with pandas and throw TypeErrors

Source code / logs

import modin.pandas as pd
data = {
        "col1": 1.0,
        "col2": np.datetime64("2011-06-15T00:00"),
        "col3": np.array([3] * 4, dtype="int32"),
        "col4": "foo",
        "col5": True,
}
modin_df = pd.DataFrame(data)
modin_df.median(axis='rows', skipna = False, numeric_only = False)

Should throw a TypeError but returns

col1    1.0
col3    3.0
col5    1.0
dtype: float64

as if numeric_only=True
