DataFrame.to_latex() does not have LaTeX caption and label support

xref PR25339

LaTeX captions and labels are not supported in longtable environments produced by DataFrame.to_latex(). Having this would mean further automation of workflow when writing LaTeX reports containing tables whose data resides in a dataframe.

DataFrame.to_latex() could also be enhanced to produce a nested table/tabular environment containing the caption and label provided by the user when longtable=False.
